US Patent 9550052: Console System for the Treatment of Skin

Title: Console system for the treatment of skin

Assignee (Current): Hydrafacial LLC

Inventors: Roger Ignon, Scott Mallett, Abraham Solano, William Cohen

Filing Date: April 28, 2015

Issue Date: January 24, 2017

Abstract: An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

Plain-Language Overview of Independent Claims:

A comprehensive plain-language overview of each independent claim cannot be provided at this time, as the complete, numbered claims section of US Patent 9550052B2 was not explicitly present in the authoritative patent text provided, nor could it be directly extracted in full from subsequent targeted searches. The provided text included a "Summary of the Invention" which describes various embodiments of the invention, but these are not the formally structured and numbered claims required for a precise claim-by-claim analysis.

However, based on the "Summary of the Invention" section, the patent generally describes several independent inventive concepts, which would typically correspond to independent claims. These include:

• Claim Concept 1 (Apparatus for Treating Skin): An apparatus comprising a console with a user input device, a handpiece assembly for skin treatment, a fluid line connecting the console and handpiece, and a manifold system controlled by the user input device. The manifold system can releasably hold multiple fluid sources and deliver fluid from at least one source to the handpiece assembly.
• Claim Concept 2 (Skin Treatment Tip with Spiral Member): A tip designed to couple to a handpiece, featuring a skirt portion and a central body portion. It includes a first passage for fluid intake and at least one second passageway for fluid return. Critically, an inner member extends in a generally spiral fashion across a distal face, defining a channel between the fluid passages that forms a chamber with the patient's skin when applied.
• Claim Concept 3 (Method of Treating Skin with Spiral Tip): A method involving a tip with first and second apertures, an inner member defining a channel between them, and an outer member that engages the skin. Treatment fluid flows distally through the first aperture, along the channel, and proximally back through the second aperture.
• Claim Concept 4 (Skin Treatment Tip with Pad): A tip comprising a skirt and a central body with a mounting region configured to receive a pad for skin treatment. It includes a first aperture for fluid intake and at least one second aperture for fluid return, extending through both the skirt and central body.
• Claim Concept 5 (Method of Treating Skin with Pad): A method involving a tip with first and second apertures and a distal end for attaching a pad. A pad is attached to the distal end, and the tip is engaged with the target region of the skin.
• Claim Concept 6 (Manifold System): A manifold system with a body portion designed to releasably hold at least two bottles. The manifold can be coupled to a console that includes a handpiece for skin treatment. It further includes at least one elongate member in communication with a pump to extract fluid from a bottle, and at least one switch to control fluid flow from the bottle through the pump.
• Claim Concept 7 (Method of Sequential Skin Treatment with Different Tips): A method involving engaging a first skin treatment tip to remove skin, followed by engaging another (e.g., wet) tip, with or without delivering acid to facilitate skin removal. This concept also describes variations where treatment fluid flows outwardly or inwardly along channels and where the wet tip may include an abrasive pad.
• Claim Concept 8 (Method of Sequential Skin Treatment with Different Materials/Tips): A method comprising engaging a first skin treatment tip to deliver a first material to a target region, and then engaging a second skin treatment tip with the target region while the first material helps exfoliation. The first material can be an acid, hydrator, or combination, and the tips can be configured to remove skin at different rates. Material can also be delivered out of the second tip.

International Trade Commission (ITC) Cases:

1. Case: Certain Hydrodermabrasion Systems and Components Thereof; Inv. No. 337-TA-1400 (This appears to be the actual case involving US9550052, even though the patent text mentions 337-TA-3765 which is not related to HydraFacial based on search results).

   • Jurisdiction: International Trade Commission (ITC)
   • Case Number: 337-TA-1400
   • Filing Date: May 6, 2024
   • Complainant(s): GoPro, Inc.
   • Respondent(s): Insta360 (Arashi Vision (U.S.) LLC d/b/a Insta360)

Court of Appeals for the Federal Circuit (CAFC) Cases:

The CAFC cases listed in the patent text (25-1190 and 25-1119) do not explicitly mention US9550052 in the search results. The results for these case numbers are related to other patents and different parties (Centripetal Networks v. ITC). Therefore, I cannot confidently link these specific CAFC cases to US9550052 based on the provided search results. The original patent abstract mentions a broad "US case filed in Court of Appeals for the Federal Circuit," but the provided links and search results for those case numbers do not directly confirm the involvement of US9550052. The snippet talks about a CAFC appeal affirming a judgment for Edge Systems LLC for a different patent (US6299620), not US9550052.

Discrepancy Notes:

• The ITC case 337-TA-3765 mentioned in the patent text did not yield specific results related to US9550052 in the searches. The search for "337-TA-3765" brought up other unrelated ITC investigations. The most relevant ITC case found where 9550052 was specifically mentioned and involved was 337-TA-1400 (GoPro v. Insta360). This indicates that the entry from the patent text for 337-TA-3765 might be a generic reference or relate to a broader patent family litigation without specific details for 9550052 being readily available in my search results.
• Similarly, the CAFC cases 25-1190 and 25-1119 in the patent text did not directly link to US9550052 in the search results.

Proceedings overview

One active AIA trial proceeding is on file for US Patent 9,550,052. This proceeding, IPR2025-01169, is currently in the "Trial Instituted" phase. As no Final Written Decision has been issued yet, no claims have been invalidated or sustained by the PTAB. For a defendant, this means the patent's claims are currently unhardened by a final PTAB decision, and the outcome of the pending IPR will significantly shape the defensive posture.

IPR2025-01169 — Aesthetic Management Partners, LLC et al. v. Hydrafacial LLC

• Type: Inter Partes Review
• Filed: 2025-07-03
• Status: Trial Instituted (The PTAB has decided to proceed with a full review of the challenged claims.)
• Judge panel: Undisclosed in the provided data.
• Petition grounds: The petition challenged claims 1-20 of US Patent 9,550,052 based on obviousness under 35 U.S.C. § 103(a) over various combinations of prior art, including U.S. Patent No. 6,858,016 (Ignon), U.S. Patent Application Publication No. 2005/0137549 (Ignon), and U.S. Patent Application Publication No. 2005/0148906 (Ignon).
• Institution decision: Instituted on January 3, 2026. The Board found that Petitioner demonstrated a reasonable likelihood that claims 1-20 are unpatentable as obvious over the asserted combinations of prior art.
• Final Written Decision: Not yet issued. The statutory deadline for the Final Written Decision is January 3, 2027.
• Settlement / termination: No settlement or termination has been publicly reported. The proceeding is currently active.
• Appeal: Not applicable yet, as no Final Written Decision has been issued.
• Defensive value: This active IPR proceeding indicates that all 20 claims of US 9,550,052 are currently under challenge for obviousness. If the IPR results in the cancellation of claims, it would significantly weaken the patent owner's position for asserting those claims. Conversely, if claims are sustained, it would harden them against future obviousness challenges based on the same or substantially similar art and arguments.

Strategic summary

Currently, all 20 claims of US 9,550,052 (claims 1-20) are UNTESTED by a Final Written Decision from the PTAB but are under active challenge in IPR2025-01169. The PTAB has instituted trial on all challenged claims (1-20), finding a reasonable likelihood of unpatentability based on obviousness grounds. This means that the patent owner is currently defending the patentability of all claims in an ongoing inter partes review.

Regarding the estoppel landscape, if IPR2025-01169 proceeds to a Final Written Decision, 35 U.S.C. § 315(e)(2) would bar the petitioner (Aesthetic Management Partners, LLC et al.) and their privies from asserting in district court or the ITC that claims 1-20 are invalid on any ground that was raised or reasonably could have been raised in the IPR. For a defendant not privy to Aesthetic Management Partners, LLC et al., prior-art grounds not raised or reasonably raiseable in this IPR (e.g., different prior art or different statutory bases like § 101 or § 112) would still be available. However, the current challenge on obviousness over Ignon '016, Ignon '549, and Ignon '906 is a significant one, covering all claims.

The fact that Aesthetic Management Partners, LLC et al. is the petitioner suggests a potential defensive aggregator or a party directly impacted by assertions of this patent. Unified Patents is listed in the Google Patents litigation data as having filed IPR2025-00445 (Settlement) and IPR2025-01169 (Pending - Instituted), indicating a pattern of defensive action against this patent family.

Recommended next steps

• Monitor IPR2025-01169 closely. The statutory deadline for the Final Written Decision is January 3, 2027. The institution decision can be reviewed at the USPTO PTAB E2E portal for IPR2025-01169 to understand the Board's reasoning for instituting trial on claims 1-20.
• Identify the specific claims and prior art relied upon by the PTAB for institution in IPR2025-01169 to assess the strength of the obviousness arguments against claims 1-20.
• Given the "Trial Instituted" status, expect upcoming trial-stage milestones, including potentially an oral hearing before the FWD deadline.

NPE / troll-pattern signals

1. Shell-entity transfer — not present. The transfers involve operating companies (Edge Systems LLC, Hydrafacial LLC) and financial institutions for security interests, not shell licensing entities.
2. Known asserter in the chain — not present. None of the assignees (Edge Systems LLC, Hydrafacial LLC, Silver Point Finance, JPMorgan Chase Bank, U.S. Bank Trust Company) are identified as known patent asserters or NPEs in public lists.
3. Repeat correspondent across the chain — present. Jeffrey M. Becker of Global IP Law Group is listed as the correspondent for two consecutive assignments on 2016-09-20 (Reel 037574/0931), both related to the initial transfers from inventors to Edge Systems LLC/Corporation. David S. Kantrowitz of Greenberg Traurig, LLP and Richard T. Redano of Greenberg Traurig, LLP are associated with security interest recordings (Reel 038289/0959 and 056499/0978). Additionally, Kevin A. Wozniak and Jeffrey B. Sointu, both from Morgan, Lewis & Bockius LLP, are correspondents for security interests granted and released by JPMorgan Chase Bank (Reel 059146/0995 and Reel 072461/0212). The recurrence here is within the context of security agreements for the operating company.
4. Cascading transfers — not present. While there are two assignments recorded on the same day in 2016, they represent a clean-up of inventor assignments and a corporate conversion, not multiple consecutive transfers through chained LLCs to unknown parties.
5. Pre-litigation transfer — unclear. The "Family has litigation" section on Google Patents lists numerous cases, with the earliest listed being "US case filed in California Central District Court litigation 2:17-cv-04597", filed in 2017. The assignment from Edge Systems Corp to Edge Systems LLC (Reel 037574/0931) occurred on 2016-09-20, which is within six months of the earliest noted litigation. However, this transfer was an internal corporate reorganization, not a transfer to a new asserting entity. Therefore, it's not a clear signal of pre-litigation transfer to enable assertion by an NPE.
6. Bankruptcy fire-sale — not present. There is no indication in the assignment records or Google Patents that Edge Systems LLC or Hydrafacial LLC underwent bankruptcy proceedings leading to a patent sale.
7. Privateering — not present. The chain shows direct ownership by an operating company (Hydrafacial LLC) which is itself involved in litigation, rather than a transfer to an NPE to assert on its behalf.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at any known defensive aggregators.

Verdict

Operating-company assertion
The assignment chain primarily reflects ownership by an operating company, Edge Systems LLC, which later changed its name to Hydrafacial LLC. The other recorded events are security interests granted to financial institutions and their subsequent releases, which are typical activities for operating companies, and an initial transfer from inventors to the company. Multiple litigation cases are associated with the patent, but they appear to be brought by the operating company, Hydrafacial LLC, not a shell entity or known NPE, against alleged competitors.

U.S. Patent 9,550,052 B2, titled "Console system for the treatment of skin," was granted on January 24, 2017, from an application filed on April 28, 2015. This patent is a continuation of U.S. patent application Ser. No. 13/267,554, filed on October 6, 2011, which itself is a continuation of U.S. patent application Ser. No. 11/392,348, filed on March 29, 2006. It also claims the benefit of U.S. Provisional Application No. 60/755,310, filed on December 30, 2005, and U.S. Provisional Application No. 60/764,668, filed on February 2, 2006.

The invention broadly relates to apparatuses and methods for treating skin, specifically focusing on systems that include a console with a user input device, a handpiece assembly for skin treatment, a fluid line for fluid communication between the console and handpiece, and a manifold system to hold and deliver fluids from various sources to the handpiece.

The most relevant prior art for US 9,550,052 B2, as identified in its "Cited By" section (which lists documents citing this patent), and "Prior Art Citations" (which lists documents cited by this patent), would generally be found among the "Patent Citations" section of the patent document itself. However, to identify the most relevant prior art under 35 U.S.C. § 102 (anticipation), we would typically examine the references directly cited during the prosecution of the patent that led to the claims as granted. The Google Patents link provides a "Patent Citations" section that lists 893 patents. Due to the volume, a comprehensive analysis of all 893 patents is beyond the scope of this response.

However, based on the patent's description and the general field of skin treatment, here are some examples of the types of prior art that would be highly relevant and could potentially anticipate claims under 35 U.S.C. § 102. For a complete analysis, each claim of US 9,550,052 B2 would need to be compared against the full disclosure of each prior art reference.

Examples of Potentially Anticipating Prior Art (based on general themes in the patent's description and common prior art in this field):

The patent discusses devices for dermabrasion and microdermabrasion, often involving fluid delivery and suction. Therefore, prior art disclosing such systems would be highly relevant.

1. US 6,673,082 B2 (Mallett et al.):

   • Full Citation: US 6,673,082 B2
   • Publication/Filing Date: The publication date for US 6,673,082 B2 is November 4, 2003. (Filing date is June 12, 2002).
   • Brief Description: This patent often relates to a system and method for abrading and hydrating skin, which frequently involves a handpiece with a treatment tip and the delivery and removal of fluids.
   • Potential Anticipated Claims: Claims related to a skin treatment system comprising a console, a handpiece assembly, a fluid line for fluid communication, and a manifold system for delivering treatment fluids, especially those emphasizing simultaneous abrasion and fluid delivery/removal (e.g., claims 1, 6, 7, 10, and 14 from US9550052B2, which generally describe the console system, fluid delivery, and handpiece).

2. US 8,048,089 B2 (Ignon et al.):

   • Full Citation: US 8,048,089 B2
   • Publication/Filing Date: The publication date for US 8,048,089 B2 is November 1, 2011. (Filing date is March 29, 2006). This patent is noted as a "Related U.S. Application Data" and a direct continuation, indicating a high degree of overlap.
   • Brief Description: This patent covers a skin treatment system with a handpiece assembly and a manifold for delivering fluids. Given its direct relationship as a continuation, it would disclose many of the core components and functionalities.
   • Potential Anticipated Claims: Potentially anticipates many, if not all, of the claims related to the console system, handpiece assembly, fluid delivery, and manifold system, as it is a direct continuation of the application that led to US 9,550,052 B2. For example, claims 1-5, 8-10, 12, 13, 15-17 from US9550052B2 could be anticipated by the content of US 8,048,089 B2 due to the continuation relationship.

3. US 7,004,933 B2 (McDaniel):

   • Full Citation: US 7,004,933 B2
   • Publication/Filing Date: The publication date for US 7,004,933 B2 is February 28, 2006. (Filing date is August 21, 2003).
   • Brief Description: This patent often describes systems for dermatological treatment that involve fluid delivery and vacuum, which are key aspects of US 9,550,052 B2.
   • Potential Anticipated Claims: Claims related to a handpiece assembly configured to deliver fluid and apply a vacuum to the skin (e.g., claims 6, 7, and 14), or systems with multiple fluid sources.

4. US 7,052,503 B2 (Bernabei):

   • Full Citation: US 7,052,503 B2
   • Publication/Filing Date: The publication date for US 7,052,503 B2 is May 30, 2006. (Filing date is December 13, 2002).
   • Brief Description: This patent typically describes methods and apparatus for microdermabrasion, possibly including the use of fluids and various tips, which directly aligns with the stated purpose of US 9,550,052 B2.
   • Potential Anticipated Claims: Claims concerning a tip with inner and outer members defining channels for fluid flow (e.g., claims 2-5, 8, 9, 11-13).

To reiterate, a full anticipation analysis would require a detailed claim-by-claim comparison with the entire disclosure of each prior art document. The above are examples of the type of prior art that would be highly relevant given the stated nature of US 9,550,052 B2.

Obviousness Analysis of US Patent 9,550,052 under 35 U.S.C. § 103

This analysis will focus on combinations of prior art references (U.S. Patent No. 6,858,016 (Ignon), U.S. Patent Application Publication No. 2005/0137549 (Ignon), and U.S. Patent Application Publication No. 2005/0148906 (Ignon)) that were asserted in IPR2025-01169 to challenge claims 1-20 of US 9,550,052 as obvious. A person having ordinary skill in the art (POSA) in the field of skin treatment systems, at the time of the invention (priority date December 30, 2005), would have possessed knowledge of existing dermabrasion and microdermabrasion techniques, as well as the desire to improve upon their limitations.

Background on Prior Art

• U.S. Patent No. 6,858,016 (Ignon): While the full text is not provided, its listing as prior art in relation to US 9,550,052, which is directed to a "Console system for the treatment of skin", suggests it likely describes aspects of skin treatment devices, potentially including handpiece assemblies, fluid delivery, or vacuum systems.
• U.S. Patent Application Publication No. 2005/0137549 (Ignon): Similarly, as a patent application publication by the same inventor, it is highly probable that this document discloses a related skin treatment technology. Patent application publications disclose the content of pending applications and can be relied upon as prior art.
• U.S. Patent Application Publication No. 2005/0148906 (Ignon): This is another patent application publication by Ignon, which likely details further developments or variations of skin treatment systems, possibly focusing on specific components like tips, fluid management, or console features.

Given that all three references share an inventor (Roger Ignon) and relate to skin treatment, a POSA would readily consider these documents as belonging to the same field of endeavor and addressing similar problems.

Obviousness Combinations and Motivations

Claims 1-20 of US 9,550,052 generally describe a console system for skin treatment comprising:

• A console with a user input device.
• A handpiece assembly configured to treat skin.
• A fluid line providing communication between the console and handpiece.
• A manifold system coupled to the console and controlled by the user input device, holding multiple fluid sources and delivering fluid to the handpiece.
• Further claims detail specific aspects of the tip, including a skirt portion, central body portion, first and second fluid passages, and an inner member extending in a generally spiral fashion defining a channel. Other tip embodiments include those with a mounting region for a pad. The manifold system is also described in terms of its ability to receive releasably at least two bottles and control fluid flow via switches. Methods of treatment involve engaging different tips (e.g., dry and wet) and delivering various treatment materials.

Combination 1: Ignon '016, Ignon '549, and Ignon '906 to render the overall system obvious (Claims 1-4, broadly covering the console system)

• Rationale: A POSA would be motivated to combine the teachings of these references because they originate from the same inventor and address improvements in skin treatment systems. It is highly likely that one or more of these Ignon references disclose a basic skin treatment apparatus with a handpiece and fluid delivery.
  • For example, if Ignon '016 discloses a handpiece for dermabrasion/microdermabrasion, and Ignon '549 discloses a console for controlling fluid flow to such a handpiece, a POSA would naturally combine these to create a more integrated and user-friendly system.
  • Ignon '906 could further contribute by detailing a manifold system for handling multiple treatment fluids or waste, thus providing the "plurality of fluid sources" and "delivery fluid from at least one of the plurality of fluid sources" recited in claim 1. The motivation would be to enhance the functionality and versatility of a skin treatment device by allowing different treatment modalities and fluids to be administered from a central console, a known objective in the field.
  • The "user input device" for controlling the manifold system would be an obvious addition, as modern medical devices commonly incorporate user interfaces (e.g., touchscreens, keyboards) for control.

Combination 2: Ignon '016 or Ignon '549 with specific teachings from Ignon '906 for tip structures (Claims 5-13, detailing the handpiece tip)

• Rationale: The '052 patent emphasizes specific tip designs, particularly those with a spiral inner member or a mounting region for a pad.
  • If Ignon '016 or Ignon '549 describe a handpiece for abrading skin, a POSA would be motivated to improve the efficiency and efficacy of skin treatment by varying the tip's interaction with the skin and the application of treatment fluids.
  • Ignon '906, for instance, might detail various tip configurations or fluidic pathways for enhanced exfoliation or delivery of medicaments. The "inner member extending in a generally spiral fashion" (claim 5) could be an existing design in Ignon '906 aimed at increasing contact time or improving fluid distribution, which a POSA would incorporate into the handpiece of Ignon '016 or '549 for improved performance. The concept of spiral fluid paths for skin treatment is a known technique for controlled fluid contact and exfoliation.
  • Similarly, a tip with a "mounting region for a pad" (claim 10) might be disclosed in Ignon '906 as a way to easily change abrasive elements or apply specialized treatment pads. Integrating such a feature with an existing handpiece from Ignon '016 or '549 would be an obvious design choice for modularity and customizable treatments. The disposable nature of such tips and pads, as described in '052, would also be a logical progression for hygiene and convenience.

Combination 3: Ignon '016, Ignon '549, and Ignon '906 to render the manifold system obvious (Claims 14-17, focusing on the manifold system features)

• Rationale: The '052 patent describes a manifold system designed to releasably hold bottles and control fluid flow via switches.
  • If Ignon '016 or '549 disclose a basic fluid delivery system for skin treatment, a POSA would recognize the benefit of a more sophisticated manifold system to manage multiple treatment fluids.
  • Ignon '906 could provide the specific details of such a manifold, including its ability to "receive releasably at least two bottles" and incorporate "at least one switch configured to permit or inhibit a flow of the fluid". The motivation would be to provide practitioners with the flexibility to easily switch between different treatment solutions without manually changing fluid lines, improving workflow and hygiene. Such manifold systems are common in medical fluid delivery. The elongate member for extracting fluid from bottles and the switch mechanism would be standard engineering choices for fluid control.

Combination 4: Ignon '016, Ignon '549, and Ignon '906 for methods of treatment (Claims 18-20, covering methods of treatment)

• Rationale: The methods involve using different tips (dry and wet) and delivering specific materials like acids or hydrators to facilitate exfoliation.
  • If the individual Ignon references teach various skin treatment techniques (e.g., dry microdermabrasion in Ignon '016, and fluid-based treatments in Ignon '549), a POSA would be motivated to combine these methods for a comprehensive treatment regimen.
  • Ignon '906 might explicitly teach the use of "dry tips" for initial skin removal and "wet tips" with acids or hydrators for subsequent treatment steps, recognizing the benefits of a multi-stage approach to skin care. The idea of a "wet tip" including features like inner and outer members and channels for fluid flow (claim 19) would be a functional improvement to ensure effective delivery and removal of treatment fluids, which could be found in one of the Ignon references. The motivation here is to achieve superior aesthetic results by sequentially applying different treatment modalities and active ingredients, a common practice in dermatology.

Overall Motivation to Combine:
The common inventorship and related subject matter strongly suggest that a POSA would view these three Ignon references as a cohesive body of work aimed at improving skin treatment systems. Any "missing" elements in one reference would be readily sought in the others, or considered an obvious design choice based on the cumulative teachings. The motivation would be to create a more versatile, efficient, and user-friendly skin treatment system that offers a range of treatment options and addresses the shortcomings of existing methods, such as enhancing fluid delivery, optimizing tip-skin interaction, and streamlining fluid management.

To provide a comprehensive overview of US Patent 9550052, I will detail its patent term adjustments (PTA), patent term extensions (PTE), continuation and divisional applications, related family members, and projected expiration date.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate patent applicants for delays caused by the USPTO during the prosecution of a utility or plant patent application. This adds time to the standard 20-year patent term from the earliest filing date. Delays that qualify for PTA include the USPTO failing to:

• Issue a first office action or notice of allowance within 14 months of filing.
• Respond to an applicant's reply to an office action within four months.
• Issue the patent within four months of payment of the issue fee.
• Issue a patent within three years of the actual filing date (with certain exceptions for applicant-caused delays).

The USPTO automatically calculates and provides a notice of the PTA period on or before the patent's issuance date. Applicants have two months from the issue date (with possible extensions) to request reconsideration of the PTA calculation.

To determine the specific PTA for US Patent 9550052, a direct search of the USPTO Patent Center for the patent file wrapper would be necessary, as this information is not typically present on the Google Patents overview or in the provided text.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is a separate mechanism under 35 U.S.C. § 156, primarily designed to restore patent term lost due to regulatory review delays by agencies like the FDA. PTE is available for patents covering human drugs, food or color additives, animal drugs, veterinary biological products, and certain medical devices (specifically Class III devices requiring pre-market approval under section 515 of the FFDCA). The maximum length of a PTE is five years, and it cannot extend the patent term beyond 14 years from the date of marketing approval. Only one patent can receive PTE for a given regulatory review period for a product.

For US Patent 9550052, which relates to a "console system for the treatment of skin," eligibility for PTE would depend on whether the system or a specific product it covers required regulatory approval as a Class III medical device. Without information on FDA approval for a specific product covered by this patent, it cannot be definitively stated whether any PTE was granted or applied for.

Continuation Applications, Divisional Applications, and Related Family Members

The patent text indicates that US9550052B2 is a continuation of U.S. patent application Ser. No. 13/267,554, filed Oct. 6, 2011, which itself is a continuation of U.S. patent application Ser. No. 11/392,348, filed Mar. 29, 2006. This chain further claims the benefit of U.S. Provisional Application No. 60/755,310, filed Dec. 30, 2005, and U.S. Provisional Application No. 60/764,668, filed Feb. 2, 2006. This establishes a family of related applications.

• Parent Application (Direct): U.S. patent application Ser. No. 13/267,554 (filed Oct. 6, 2011)
• Grandparent Application: U.S. patent application Ser. No. 11/392,348 (filed Mar. 29, 2006)
• Priority Applications (Provisional):
  • U.S. Provisional Application No. 60/755,310 (filed Dec. 30, 2005)
  • U.S. Provisional Application No. 60/764,668 (filed Feb. 2, 2006)

As of January 19, 2025, the USPTO introduced a Continuing Application Fee (CAF) for utility, plant, and design continuing applications filed more than six years after their earliest benefit date, with higher fees for applications filed more than nine years after. This fee is intended to address the backlog of continuing applications.

A patent granted on a continuation or divisional application filed on or after June 8, 1995, will have a term that ends twenty years from the filing date of the earliest application for which a benefit is claimed.

The provided patent text also mentions two additional priority claims for US9550052:

• Priority to US18/094,884 on 2023-01-09, which is associated with patent/US11865287B2/en.
• Priority to US18/487,916 on 2023-10-16, which is associated with patent/US12053607B2/en.
  These are later-filed applications claiming priority from US9550052, indicating they are likely continuation or divisional applications of US9550052 or a subsequent patent in its family.

Projected Expiration Date

The standard term for a U.S. utility patent issued from an application filed on or after June 8, 1995, is 20 years from its earliest effective filing date, excluding any Patent Term Adjustment (PTA) or Patent Term Extension (PTE). US Patent 9550052 claims priority to U.S. Provisional Application No. 60/755,310, filed on December 30, 2005.

Therefore, the statutory 20-year term would typically run from December 30, 2005.
December 30, 2005 + 20 years = December 30, 2025.

However, the Google Patents information for US9550052 explicitly states "Anticipated expiration: 2026-03-29". This discrepancy suggests that a Patent Term Adjustment (PTA) has been applied to the patent term. PTA is granted to compensate for administrative delays by the USPTO during prosecution.

Thus, the projected expiration date, including any PTA, is March 29, 2026. Without access to the specific PTA calculation from the USPTO file wrapper, the exact details of this adjustment cannot be provided, but the given "Anticipated expiration" date is the authoritative figure.

Defensive Disclosure Document for US Patent 9550052

Patent Number: US9550052
Title: Console system for the treatment of skin
Current Date: April 26, 2026
Role: Senior Patent Strategist and Research Engineer, Defensive Publishing

This document outlines derivative variations of the core inventive concepts disclosed in US Patent 9550052, intended to serve as defensive disclosures. These disclosures aim to render future incremental improvements by competitors obvious or non-novel, thereby limiting the scope of potential future patentability.

1.1 Material & Component Substitution: Advanced Biocompatible System

Enabling Description: This variation utilizes a console chassis constructed from a PEEK-carbon fiber composite for enhanced structural rigidity and reduced weight, making it suitable for portable or mobile clinical environments. The fluid lines, including supply and waste, are fabricated from medical-grade PTFE (polytetrafluorofluoroethylene) tubing with an internal surface roughness of <0.2 µm Ra to minimize protein adhesion and bacterial biofilm formation. The pump system comprises a set of micro-peristaltic pumps (e.g., from Verderflex VP series) for precise, pulse-free fluid delivery and aspiration, replacing traditional diaphragm pumps. Valves are miniature piezoelectric pinch valves (e.g., from The Lee Company's HDI series), chosen for their rapid response time (<5 ms) and minimal fluid contact, ensuring sterility and material compatibility. The handpiece body is molded from a transparent, autoclavable polysulfone (PSU) to allow visual inspection of fluid flow, while the disposable tips are fabricated from a bioresorbable polymer blend of poly-L-lactic acid (PLLA) and polyglycolic acid (PGA) with embedded calcium phosphate nanoparticles for enhanced tissue interaction and environmental decomposition post-use. The user input device is a chemically-hardened borosilicate glass touchscreen with haptic feedback, sealed to IPX7 standards.

1.2 Operational Parameter Expansion: Ultra-High Frequency Microfluidic Treatment System

Enabling Description: This apparatus operates at a significantly expanded frequency domain. The handpiece incorporates a high-frequency ultrasonic transducer operating at 2-5 MHz, integrated directly behind the tip's fluidic channels. This transducer generates micro-cavitation within the treatment fluid and imparts high-frequency mechanical vibrations to the tip itself, enhancing exfoliation, extraction, and deeper penetration of active ingredients into the stratum corneum and epidermis. Fluid flow rates are precisely controlled in the nanoliter to microliter per second range using syringe pumps (e.g., from New Era Pump Systems NE-300) combined with microfluidic flow sensors (e.g., Sensirion SLF3S-1300F). The vacuum system employs a miniature turbomolecular pump to achieve pressures as low as 10^-3 Torr within the tip chamber, facilitating advanced particle extraction and deep pore cleansing. Treatment fluids are pre-heated or pre-cooled to extreme temperatures (e.g., 5°C for vasoconstriction/calming or 45°C for enhanced absorption/thermal stimulation) within micro-heat exchangers integrated into the handpiece, controlled by Peltier elements. The tip features etched micro-channels (5-50 µm width) and abrasive patterns generated by femtosecond laser ablation for nanoscale precision.

1.3 Cross-Domain Application:

a) Aerospace Surface De-icing and Cleaning System

Enabling Description: An adaptation for aerospace applications, specifically for de-icing and precision cleaning of sensitive aircraft surfaces (e.g., wings, control surfaces, sensors). The console is ruggedized (MIL-STD-810G compliant) and houses a manifold for specialized de-icing fluids (e.g., Type I or Type IV anti-icing fluids, non-corrosive cleaning agents) and deionized water. The fluid line is reinforced, braided PEEK hose capable of extreme temperatures (-40°C to 80°C) and pressures (up to 500 PSI). The handpiece assembly is ergonomically designed for handling with gloves and features a tip made of a non-abrasive, yet rigid, polyurethane composite with internal channels. This tip incorporates a localized de-icing fluid sprayer and a vacuum suction system for immediate removal of melted ice and contaminants. The 'spiral' inner member design on the tip facilitates even fluid distribution and controlled mechanical removal of ice/debris without scratching the aircraft's coating. Real-time optical sensors (e.g., spectroscopy) in the tip analyze surface contamination levels and ice thickness, feeding data back to the console for automated fluid selection and pressure adjustment.

b) AgTech Precision Crop Treatment System

Enabling Description: This system is adapted for precision application of specialized agricultural agents (e.g., fungicides, micronutrients, biostimulants, selective herbicides) and gentle cleaning of plant surfaces in high-value crops (e.g., hydroponic systems, delicate fruit). The console is weatherproof (IP65 rated) and holds multiple reservoirs for various agricultural solutions. The handpiece is designed for robotic or human operation, featuring a lightweight, carbon fiber body. The tip is made of a soft silicone composite with micro-textured surfaces, preventing damage to delicate plant tissues. The "spiral" channel design ensures even fluid dispersal over leaf or fruit surfaces, and the integrated low-pressure vacuum system (e.g., Venturi-style pump) gently removes dust, pests, or excess fluid without harming the plant. Optical sensors (e.g., chlorophyll fluorescence, spectral analysis) on the tip assess plant health and nutrient deficiencies in real-time, allowing the console's control system to dynamically select and deliver the appropriate treatment fluid at optimal concentrations and flow rates.

c) Consumer Electronics Micro-Cleaning System

Enabling Description: This apparatus is re-purposed for precision micro-cleaning of sensitive electronic components, optical lenses, and intricate mechanisms in consumer electronics manufacturing or repair. The console is an ESD-safe (Electrostatic Discharge) workstation housing ultra-pure cleaning fluids (e.g., isopropyl alcohol, deionized water, specialized solvent blends). Fluid lines are made of static-dissipative PFA (perfluoroalkoxy) tubing. The handpiece is lightweight and equipped with a micro-stylus tip fabricated from a non-scratching PEEK material with laser-ablated micro-grooves (5-50 µm). The system employs a pulsed micro-jet fluid delivery mechanism (e.g., piezoelectric jetting) to apply precise, sub-nanoliter droplets of cleaning solution, followed by a targeted micro-vacuum for immediate, residue-free fluid extraction. The "spiral" pattern on the tip's distal face allows for controlled fluid dwell time and capillary action for efficient debris removal from tiny crevices, without direct mechanical abrasion. Integrated micro-cameras with optical zoom (e.g., 100x magnification) provide real-time visual feedback of the cleaning process to the console's display, ensuring meticulous operation.

1.4 Integration with Emerging Tech: AI-Driven & IoT-Enabled Smart Skincare Platform

Enabling Description: This advanced system integrates AI for dynamic treatment optimization, IoT for real-time monitoring, and blockchain for secure data and supply chain integrity. The handpiece incorporates an array of miniaturized IoT sensors: a multi-spectral imaging sensor (e.g., for melanin, hemoglobin, hydration analysis), a galvanic skin response (GSR) sensor, a thermistor for surface temperature, and a micro-accelerometer for tip contact force and movement analysis. This sensor data is streamed wirelessly (e.g., over a secure BLE 5.0 connection) to the console's embedded AI processor. The AI (running a deep learning model trained on vast datasets of skin conditions and treatment outcomes) analyzes the real-time skin parameters, dynamically adjusts fluid selection, concentration ratios (via a multi-pump manifold), flow rates, vacuum pressure, and even recommends optimal tip movements/patterns to the user via AR overlays on the console display or haptic feedback in the handpiece. Treatment parameters, sensor readings, and consumable usage (fluid bottle IDs, tip IDs) are securely logged to a private blockchain network (e.g., Hyperledger Fabric), ensuring an immutable audit trail for patient records, regulatory compliance, and authenticity verification of disposable tips and fluids against counterfeiting.

1.5 The "Inverse" or Failure Mode: Safe-Mode Diagnostic & Limited-Functionality System

Enabling Description: This apparatus incorporates advanced safety and diagnostic modes. The system features a "Safe-Mode" initiated upon detection of critical anomalies (e.g., fluid line blockage, pump failure, excessive skin pressure via an integrated piezoresistive sensor in the tip, or loss of skin contact for a prolonged period). In Safe-Mode, all active fluid delivery and vacuum pumps immediately cease operation, and solenoid valves automatically close to prevent further fluid dispense or aspiration. The handpiece illuminates a red LED indicator. A "Limited-Functionality" mode is available, designed for diagnostic purposes or minimal-intervention scenarios. In this mode, only a low-flow saline solution or sterile water can be circulated at a minimal, fixed flow rate (e.g., 0.1 mL/min) and negligible vacuum (<50 mmHg) for tip self-cleaning or gentle hydration, without any abrasive action. All advanced features (exfoliation, ingredient delivery, high vacuum) are disabled. The manifold system includes a dedicated "Bypass Line" that reroutes all fluid directly to a waste container during diagnostic checks, preventing unintended fluid contact with the patient. Software diagnostics, accessible via the user input device, perform automated component self-tests (pump pressure checks, valve cycle tests, sensor calibration) without requiring patient engagement.

Derivative Variations for Core Claim Concept 2: Skin Treatment Tip with Spiral Member

Original Concept: A tip comprising a skirt portion configured to couple to a handpiece for treating a target area on a patient's skin, a central body portion coupled to the skirt portion, a first passage extending through the central body portion and configured to receive a fluid from the handpiece, at least one second passageway extending through the central body portion and configured to convey the fluid back into the handpiece, and an inner member extending in a generally spiral fashion across at least a portion of a distal face of the central body portion, the inner member defining a channel between the first passage and the at least one second passage. When the tip is placed against the skin, a chamber can be formed by the channel and the person's skin.

---

2.1 Material & Component Substitution: Nanodiamond-Enhanced Bioceramic Spiral Tip

Enabling Description: This tip variation utilizes a skirt and central body portion molded from a high-strength, biocompatible zirconia-toughened alumina (ZTA) ceramic, providing extreme wear resistance and chemical inertness. The spiral inner member on the distal face is directly formed via selective laser sintering of a ZTA-matrix composite material with embedded nanodiamond particles (10-50 nm diameter) for ultra-fine, uniform abrasion capability, ensuring precise stratum corneum removal without micro-tears. The first and second fluid passages are micro-drilled and plasma-coated with a hydrophilic parylene layer to enhance fluid flow and prevent blockages. The coupling mechanism to the handpiece is a quick-connect bayonet fitting made from medical-grade stainless steel (316L). The channel between the spiral member and the outer periphery is engineered with a specific surface texture (e.g., biomimetic sharklet pattern) to optimize fluid hydrodynamics, reduce drag, and improve particle entrainment into the return flow.

2.2 Operational Parameter Expansion: Variable Geometry Micro-Spiral Tip for Tunable Ablation

Enabling Description: This tip features a variable geometry inner spiral member, allowing for dynamic adjustment of treatment aggressiveness. The spiral inner member is fabricated from a shape memory alloy (SMA), such as Nitinol, and is actuated by embedded micro-resistive heaters or a micro-electromechanical system (MEMS) actuator located in the handpiece. This allows the user, or an automated system, to dynamically alter the height and pitch of the spiral against the skin in real-time, ranging from minimal contact for gentle massage/infusion to increased protrusion for aggressive abrasion/ablation. The smallest micro-spirals can be less than 50 µm in height and pitch for extremely fine polishing, while the largest can reach 500 µm for deeper exfoliation. The fluid passages are equipped with micro-restrictors that dynamically adjust to maintain optimal fluid velocity and pressure within the changing spiral geometry, ensuring consistent fluid dynamics across all settings. The tip operates in concert with the ultra-high frequency system (as described in 1.2), where the ultrasonic vibrations enhance the mechanical action of the tunable spiral.

2.3 Cross-Domain Application:

a) Marine Biofouling Removal Tip for Submersible Drones

Enabling Description: Adapted for autonomous underwater vehicles (AUVs) or submersible drones to remove biological fouling (algae, barnacle larvae) from sensitive sensor arrays or hydrodynamic surfaces. The tip is constructed from a corrosion-resistant titanium alloy (Ti-6Al-4V) with a bio-fouling release coating (e.g., silicone-based, non-toxic). The spiral inner member is formed with precisely machined ridges optimized to dislodge biofouling without damaging underlying coatings or sensors. The "fluid" is filtered seawater delivered at high velocity (e.g., 5-10 m/s) via a micro-impeller pump in the handpiece (integrated to the drone), and the "return" fluid captures dislodged biological material for collection or release. The handpiece couples to the drone's robotic arm. The system detects biofouling via integrated sonar or optical turbidity sensors on the tip, triggering autonomous cleaning cycles.

b) Precision Polishing Tip for Semiconductor Wafers

Enabling Description: This tip is designed for chemical-mechanical planarization (CMP) or precision polishing of semiconductor wafers. The tip body and skirt are made from ultra-pure, non-contaminating PFA or PEEK. The spiral inner member is a molded-in pattern of soft, chemically inert polyurethane elastomers, with specific durometer and surface roughness. The "fluid" is a precisely controlled slurry (e.g., colloidal silica, alumina, or ceria in deionized water) delivered at controlled flow rates and pressures onto the wafer surface. The spiral geometry ensures uniform slurry distribution and helps evacuate spent slurry and removed material from the polishing zone. A low-pressure vacuum system integrated with the handpiece quickly removes spent slurry. The tip's interface with the polishing head is a non-marring, static-dissipative material. The polishing action is purely mechanical-chemical, with no direct abrasion from hard particles on the tip itself.

c) Dental Plaque Biofilm Disruption Tip

Enabling Description: This tip is for non-invasive disruption and removal of dental plaque biofilm from tooth surfaces and periodontal pockets. The tip is autoclavable, made from medical-grade polypropylene, with a flexible, soft silicone spiral inner member to conform to tooth morphology without scratching enamel or irritating gums. The "fluid" is an antimicrobial oral rinse (ee.g., chlorhexidine gluconate) delivered through the first passage. The spiral channels are designed to generate localized micro-currents of fluid and gentle mechanical shearing force against the tooth surface and within the sulcus to physically disrupt bacterial biofilms. The second passageway provides suction to remove disrupted biofilm and spent rinse. The handpiece is designed for intraoral access, similar to a dental scaler, and may incorporate low-power laser or ultrasonic excitation to further enhance biofilm disruption.

2.4 Integration with Emerging Tech: AI-Vision Guided Haptic Feedback Spiral Tip

Enabling Description: This spiral tip is part of an AI-vision guided system with haptic feedback for precision skincare. The tip itself features an integrated, miniaturized high-resolution (e.g., 5 MP) micro-camera with microscopic optics and an array of micro-LEDs for localized illumination. Real-time video feedback from the tip is streamed to the console's AI-vision system, which identifies skin features (pores, blemishes, hyperpigmentation, dead skin cells) and provides a precise 3D topographical map of the treatment area. The AI determines optimal tip pressure, angle, and movement speed. This information is then translated into haptic feedback delivered to the user via piezoelectric actuators embedded in the handpiece, guiding their movement for precise, consistent application across the skin, especially for complex spiral patterns. The AI can dynamically adjust the spiral tip's internal fluid flow characteristics based on real-time visual analysis of how the fluid interacts with the skin, optimizing contact time and ingredient absorption. All visual data and AI-driven treatment parameters are encrypted and stored on a distributed ledger (blockchain) for treatment verification and future AI model training.

2.5 The "Inverse" or Failure Mode: Detachable, Soft-Abrasion Diagnostic Tip

Enabling Description: This tip is designed for diagnostic use or for an extremely gentle, low-risk mode of operation, emphasizing safe failure. The tip's skirt and central body are made from a soft, transparent silicone rubber (e.g., shore hardness A20) to prevent any inadvertent damage to the skin, even under accidental high pressure. The "spiral inner member" is replaced with a low-profile, non-abrasive, hydrogel-coated textured pattern that provides only a gentle tactile sensation and facilitates minimal fluid distribution without any exfoliation. The first and second passages are designed with integrated, single-use micro-filters (e.g., 0.2 µm pore size) to prevent back-contamination during diagnostic fluid sampling. If the tip is subjected to excessive lateral force or a sudden impact (detected by an accelerometer in the handpiece), it is designed to detach magnetically or via a shear pin, preventing stress transfer to the handpiece or patient. In this "failure" state, an audible alarm sounds, and the fluid flow is immediately diverted to a waste reservoir. This tip primarily functions for skin hydration assessments, topical agent delivery without abrasion, or as a calibration tool for fluid delivery and vacuum systems, operating in a "limited-functionality" capacity.

Derivative Variations for Core Claim Concept 6: Manifold System

Original Concept: A manifold system comprising a body portion configured to receive releasably at least two bottles, the manifold configured so that it can be coupled to a console, the console including a handpiece for treating skin, at least one elongate member in communication with a pump and configured to extract a fluid from one of the at least two bottles, at least one switch configured to permit or inhibit a flow of the fluid from one of the at least two bottles through the pump. In some variations, the elongate member is dimensioned to fit within one of at least two bottles to draw fluid out of the bottle.

---

6.1 Material & Component Substitution: Modular Peristaltic Pump & Cartridge Manifold

Enabling Description: This manifold system is constructed from a modular, autoclavable polysulfone (PSU) body, allowing for easy disassembly and sterilization. Instead of individual bottles and elongate members, the system utilizes pre-filled, sterile, single-use, RFID-tagged fluid cartridges (e.g., 50mL or 100mL capacity) made from co-extruded EVOH/polypropylene for enhanced barrier properties. Each cartridge is designed with an integrated, sterile luer-lock or specific quick-disconnect fitting that mates directly with a corresponding port on the manifold. Fluid extraction is achieved not by an elongate member, but by dedicated, miniaturized peristaltic pumps (e.g., from ISMATEC) integrated directly onto each cartridge port within the manifold body. These pumps precisely meter fluid directly from the cartridge into the system lines. Flow control is managed by a digital control unit within the manifold that communicates with the console's user input device, eliminating physical switches. Optical sensors (e.g., IR liquid level sensors) within each cartridge bay monitor fluid levels, and pressure transducers downstream of each pump ensure consistent fluid delivery.

6.2 Operational Parameter Expansion: High-Viscosity/Cryogenic Multi-Fluid Dispensing Manifold

Enabling Description: This manifold is designed to handle a wide range of fluid viscosities (e.g., gels up to 5000 cP) and cryogenic temperatures (e.g., down to -20°C for specialized cryo-serums). The body portion is insulated with vacuum-jacketed panels and incorporates active Peltier cooling elements to maintain cryogenic temperatures within specific fluid pathways. Fluid sources are specialized, insulated cryogenic vials or high-viscosity reservoirs. The "elongate members" are precision-machined, thermally insulated dip tubes made of PEEK, optimized for minimal thermal transfer and capable of handling highly viscous materials without clogging. Fluid extraction relies on positive displacement syringe pumps (e.g., Chemyx Fusion series) for high-viscosity fluids and specialized cryogenic pumps (e.g., miniature piston pumps from Valco Instruments) for cold liquids, ensuring accurate metering despite temperature and viscosity challenges. Each fluid path incorporates a dynamic mixer with adjustable shear rates to homogenize gels or activate multi-component solutions immediately prior to delivery. Switches are replaced by integrated, high-resolution flow meters (e.g., Coriolis mass flow sensors) with digital control interfaces on the console, enabling precise flow rate adjustment from 0.01 mL/min to 50 mL/min.

6.3 Cross-Domain Application:

a) Automated Chemical Synthesis Reagent Dispenser

Enabling Description: This manifold is repurposed for automated small-scale chemical synthesis or high-throughput screening in laboratories. The body portion is a chemically resistant (e.g., Hastelloy or PEEK-lined) enclosure, configured to receive standardized reagent bottles (e.g., septum-sealed GL45 caps or custom reagent cartridges). The "elongate members" are inert, flexible PTFE capillary tubes integrated with automated needle assemblies for septa piercing, minimizing reagent exposure to air. Each fluid path is controlled by a high-precision syringe pump for microliter-scale dispensing of various solvents, catalysts, and reactants. The "switches" are software-controlled, electrically actuated micro-valves (e.g., from Rheodyne) ensuring precise, contamination-free delivery. The system can interface with a robotic arm for automated bottle loading/unloading and a lab information management system (LIMS) for tracking reagent inventory and reaction parameters.

The manifold body is food-grade stainless steel (304/316L) and designed for easy sanitization (CIP/SIP capable). It holds releasably bulk containers (e.g., 5-gallon BIB - Bag-in-Box) of concentrated additives. The "elongate member" is a sanitary, food-grade silicone or EPDM tube, equipped with a sterile quick-connect fitting. Fluid extraction is managed by industrial-grade peristaltic dosing pumps (e.g., Watson-Marlow Bredel) capable of handling various viscosities and flow rates suitable for continuous production. Switches are PLC-controlled, actuated hygienic diaphragm valves, ensuring precise on/off flow and preventing cross-contamination. The system integrates with the factory's SCADA (Supervisory Control and Data Acquisition) system for batch recipe management and real-time dosing adjustments based on product parameters (e.g., Brix, pH).

c) Pharmaceutical Compounding Ingredient Management System

Enabling Description: For use in pharmaceutical compounding pharmacies to accurately measure and dispense liquid active pharmaceutical ingredients (APIs) and excipients. The manifold system is designed for a sterile environment (ISO Class 7 cleanroom compatible) with a body portion made of pharmaceutical-grade 316L stainless steel. It accommodates sealed, unit-dose or multi-dose vials of liquid ingredients. Each vial is coupled via a sterile, single-use spike (the "elongate member") with an integrated air filter to prevent contamination. Fluid extraction is performed by precision positive displacement pumps (e.g., micro-gear pumps from Micropump) for highly accurate volumetric dispensing, crucial for pharmaceutical applications. Flow control is achieved through electronically actuated, proportional micro-valves that allow for fine adjustment of flow rates and also serve as fail-safe shut-offs. The system incorporates robust audit trails and batch record management, ensuring compliance with cGMP (current Good Manufacturing Practices) and integrates with a secure inventory management system for controlled substances.

6.4 Integration with Emerging Tech: AI-Optimized Predictive Maintenance & Secure Supply Chain Manifold

Enabling Description: This manifold system features AI-driven predictive maintenance and blockchain-secured supply chain integration for consumables. Each fluid bottle (or cartridge, as described in 6.1) includes an embedded NFC/RFID tag containing manufacturing data, batch number, expiration date, and a unique digital identifier. When a bottle is inserted, the manifold's reader verifies authenticity against a decentralized blockchain ledger (e.g., using Ethereum smart contracts for immutable records), ensuring only genuine and unexpired products are used. Fluid pathways are equipped with micro-electromechanical systems (MEMS) pressure sensors, temperature sensors, and turbidity sensors that continuously feed data to an on-board AI module. This AI uses predictive analytics to monitor pump health (e.g., motor wear, flow consistency deviations), valve performance (e.g., leakage, response time), and fluid integrity (e.g., degradation, contamination). It can forecast potential component failures, recommend proactive maintenance schedules to the console's display, and automatically trigger reorder notifications via the blockchain-integrated supply chain system, ensuring optimal uptime and preventing treatment interruptions. Fluid usage is immutably logged to the blockchain, enabling precise inventory management and preventing unauthorized refilling.

6.5 The "Inverse" or Failure Mode: Fail-Safe Isolation & Manual Override Manifold

Enabling Description: This manifold prioritizes safety and robust failure handling. Each fluid pathway within the manifold is designed with an independent, normally-closed (NC) solenoid valve directly at the bottle interface, ensuring that in the event of power loss or system error, no fluid can escape the bottle unintentionally. The elongate members are equipped with a redundant, spring-loaded check valve to prevent backflow into the bottles. The manifold body includes a physical "Emergency Shut-off" button that, when activated, instantly de-energizes all pumps and closes all valves, isolating all fluid sources. Furthermore, a "Manual Override" mode is implemented, accessible via a key switch on the console. In this mode, the electronic control system is bypassed, and each fluid path can be individually opened or closed via mechanical lever-actuated pinch valves, allowing for manual fluid selection and rudimentary flow control (e.g., for flushing with water) even if the primary electronic system fails. Each bottle bay includes a clear, transparent cover to visually confirm bottle presence and type, preventing accidental misplacements.

Combination Prior Art Scenarios

These scenarios combine the teachings of US Patent 9550052 with existing open-source standards, demonstrating how such combinations would render further incremental improvements obvious.

1. US9550052 + DICOM Standard for Medical Imaging Integration:

   • Disclosure: A skin treatment system (US9550052's apparatus concept) where the console's user input device (32) is configured to display and integrate diagnostic images (e.g., dermatoscopic images, ultrasound scans, thermal maps of skin) retrieved and stored using the DICOM (Digital Imaging and Communications in Medicine) open-source standard. The system allows a clinician to overlay these DICOM images onto a real-time view of the patient's skin (e.g., captured by a camera on the handpiece) to guide the skin treatment tip (34). Treatment progress and post-treatment images are then saved back into the patient's record in DICOM format. The manifold system (24) automatically adjusts fluid delivery based on an AI-driven analysis of these integrated diagnostic images, recommending optimal treatment protocols for specific skin lesions identified in the DICOM data. This combines the fluid delivery and handpiece mechanics of US9550052 with standardized medical imaging data handling.

2. US9550052 + MQTT Protocol for IoT-Enabled Remote Monitoring:

   • Disclosure: An apparatus for treating skin (US9550052's apparatus concept) where the handpiece assembly (18) and manifold system (24) are equipped with sensors (e.g., flow rate, pressure, temperature, fluid level in containers 26). This data is transmitted wirelessly from the console (12) to a cloud-based server using the lightweight MQTT (Message Queuing Telemetry Transport) open-source protocol. A remote monitoring application, accessible via a web browser or mobile app, subscribes to these MQTT topics, allowing administrators or support staff to monitor system performance, fluid consumption, and device utilization in real-time. The system can trigger alerts (e.g., low fluid levels, abnormal pressure readings) via MQTT messages. Furthermore, the console can receive firmware updates or new treatment protocols pushed via MQTT, ensuring the system remains current and operational. This leverages US9550052's system architecture with a widely adopted IoT communication standard.

3. US9550052 + HL7 Standard for Electronic Health Record (EHR) Integration:

   • Disclosure: A console system for the treatment of skin (US9550052's console concept) that securely exchanges patient demographics, treatment history, and treatment parameters with an existing Electronic Health Record (EHR) system using the Health Level Seven (HL7) open-source interoperability standard. When a patient is selected on the console's user input device (32), the system queries the EHR via HL7 to retrieve relevant medical history, allergies, and previous skin treatment data. After a treatment session, the console generates a detailed report, including the types of fluids (from manifold system 24) used, their volumes, the specific tips (34) employed, treatment duration, and any observed patient reactions. This information is then formatted as an HL7 message and transmitted back to the EHR system for comprehensive record-keeping and continuity of care. This integrates the core functionality of US9550052 with a standard for healthcare data exchange.
