US RE48479

I am unable to provide a concise summary of US patent RE48479, including its title, assignee, inventors, filing date, issue date, abstract, and a plain-language overview of each independent claim, because a direct fetch of the patent's full text via web search has failed. My searches returned general information about how to use USPTO's patent search tools (like Patent Public Search and Patent Center) but did not provide direct access to the specific patent document RE48479.

Therefore, I do not have authoritative information to ground the requested details of the patent.

Regarding CAFC 2026 dockets for RE48479, the general search results indicate that case information for filings on or after March 1, 2012, is available through PACER, and older records require contacting the Clerk's Office. Without specific case numbers or party names related to RE48479, a comprehensive search of CAFC dockets for 2026 is not feasible with the current information and tools available to me. Therefore, I cannot confirm any ongoing litigation or related cases for RE48479.

Known litigation involving US patent RE48479 is detailed below, primarily stemming from a parallel district court case referenced in Patent Trial and Appeal Board (PTAB) proceedings.

Case 1: Happy Products, Inc. v. Ontel Products Corporation

• Plaintiff(s): Happy Products, Inc.
• Defendant(s): Ontel Products Corporation
• Jurisdiction: United States District Court for the District of New Jersey (DNJ)
• Case Number: 2:24-cv-09819
• Filing Date: The IPR documents refer to a "2002 Complaint for Patent Infringement," but also a "2012 DNJ-2-24-cv-09819 Docket Sheet". Given the IPR filing date in late 2025, the "2:24-cv-09819" case number suggests a filing date in 2024, which would be consistent with a parallel litigation. The exact filing date for 2:24-cv-09819 is not directly available in the provided snippets, but the references within the IPR suggest a complaint was filed by the patent owner against Ontel.
• Outcome or Current Status: This case is a parallel litigation to an Inter Partes Review (IPR) proceeding (IPR2025-01536) before the Patent Trial and Appeal Board (PTAB). In the IPR, Ontel Products Corporation challenged the patent, but institution of the inter partes review was denied on February 10, 2026, based on discretionary considerations under 35 U.S.C. § 314(a). The denial of institution means the validity challenge at the PTAB did not proceed. The district court litigation itself saw motions, including a motion to dismiss by the defendant, and orders denying a stay of litigation requested by the defendant. The IPR documents mention a "Pretrial Scheduling Order" and a "Joint Letter to Magistrate Judge Almonte re Dispute Concerning Stay". The specific outcome or current status of the district court case (2:24-cv-09819) itself, beyond the denial of a stay and the refusal to institute IPR, is not explicitly detailed in the provided search results.

Related PTAB Proceeding:

• PTAB Case Number: IPR2025-01536
• Petitioner: Ontel Products Corporation
• Patent Owner: Happy Products, Inc.
• Patent: U.S. Patent No. RE48,479
• Filing Date (IPR Petition): October 16, 2025
• Outcome/Status: Institution of inter partes review was denied on February 10, 2026, based on discretionary considerations. Ontel Products Corporation subsequently requested a refund of post-institution fees on April 14, 2026.

Proceedings overview

One AIA trial proceeding is on file for US patent RE48479. This proceeding, IPR2025-01536, resulted in a discretionary denial of institution, meaning the patent claims were not reviewed on the merits by the Patent Trial and Appeal Board (PTAB). Consequently, all claims of RE48479 remain untested on their patentability by the PTAB. This gives a defendant facing assertion of this patent the defensive posture that the patent's claims have not been challenged and validated by the PTAB, but the specific petitioner (Ontel Products Corporation et al.) may be estopped from re-raising similar challenges.

IPR2025-01536 — Ontel Products Corporation et al. v. Bruce Cannon et al

• Type: Inter Partes Review
• Filed: 2025-10-16
• Status: Discretionary Denial — The petition for inter partes review was denied institution by the USPTO Director on policy grounds, without a review of the merits of the patentability challenge. The last modification to the case was 2026-04-16.
• Judge panel: During the period this petition was filed and decided, institution decisions for IPRs were handled by the Director of the USPTO, often in consultation with Administrative Patent Judges (APJs), rather than a traditional three-judge panel for a merits review. [cite: 3, 4, 5, 8, 10 in the prior step] The specific Director's decision document would identify any consulting APJs or simply indicate a Director's Decision. Without the specific decision document, the names of consulting APJs (if any) are not publicly available.
• Petition grounds: The specific claims challenged and the prior art cited are not publicly available without the petition document. However, IPRs typically challenge patentability under 35 U.S.C. §§ 102 (novelty) and/or 103 (obviousness).
• Institution decision: Denied (discretionary denial). The precise date of the Director's decision is not explicitly available through general search, but the case was last modified on 2026-04-16. Given the filing date (2025-10-16), this decision falls under the USPTO's interim procedures established in March 2025, where the Director implemented a bifurcated approach to institution decisions focusing on discretionary considerations, including "settled expectations" and efficient workload management. The denial was likely based on such policy considerations rather than a determination on the merits of the challenged claims. Factors like the length of time the patent has been in force or the petitioner's prior knowledge of the patent (known as "settled expectations") frequently informed such discretionary denials during this period. [cite: 3, 9, 10 in the prior step]
• Final Written Decision (if issued): Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied; the proceeding did not reach a stage for settlement or termination on the merits.
• Appeal: Decisions to deny institution of an IPR are generally not appealable to the Federal Circuit.
• Defensive value: This proceeding indicates that the challenged claims of RE48479 were not subjected to a merits review by the PTAB and thus were neither invalidated nor confirmed as patentable in this context. While the patent owner prevailed in preventing a trial, the underlying patentability of the claims remains untested by the PTAB. The petitioner, Ontel Products Corporation et al., along with any real parties in interest or privies, may be estopped from raising the same or substantially similar invalidity grounds against RE48479 that were presented or could have been reasonably presented in this petition.

Strategic summary

All claims of RE48479 are currently UNTESTED by the PTAB on their merits. The single IPR proceeding filed against RE48479 (IPR2025-01536) resulted in a discretionary denial of institution, meaning the PTAB did not reach a decision on the patentability of the challenged claims. Therefore, no claims of RE48479 have been canceled or sustained by the PTAB.

The estoppel landscape for RE48479 is relatively clear for this specific proceeding. Under 35 U.S.C. § 315(e)(2), a petitioner (and its real parties in interest or privies) is generally estopped from asserting in a civil action or ITC investigation that a claim is invalid on any ground that the petitioner raised or reasonably could have raised during an IPR that results in a Final Written Decision. Since IPR2025-01536 was denied institution on discretionary grounds, rather than reaching a Final Written Decision, the full scope of statutory estoppel under § 315(e)(2) might not apply as broadly as it would after a full trial. However, the petitioner (Ontel Products Corporation et al.) and its privies would likely be precluded from filing another petition against RE48479 with the same or substantially similar grounds that were presented in IPR2025-01536, especially if the discretionary denial was based on factors related to the petition itself or the petitioner's conduct. New prior-art grounds or different legal theories (e.g., if the original petition only asserted §102 grounds, §103 grounds might still be available to new parties, or even the same party if it's a truly different set of claims/grounds that couldn't have been reasonably raised). For a defendant currently being asserted against (other than Ontel Products Corporation et al. and its privies), all prior-art grounds remain potentially available.

There is no pattern of multiple IPRs on this patent, nor is there any indication of aggressive PTAB appeals by the patent owner or involvement of a defensive aggregator.

Recommended next steps

Since the patent has not had any claims invalidated by the PTAB, the immediate defensive posture against assertion of RE48479 is that its patentability on the merits has not been judicially confirmed or denied by the PTAB.

For a defendant considering challenging this patent:

• Obtain the full claims and specification of RE48479: Access the full text of US Patent RE48479 via a dedicated USPTO patent search portal (e.g., Patent Public Search, Patent Center) to thoroughly understand the scope of the claims. General web searches have not yielded the complete, verifiable claim set.
• Review the institution decision for IPR2025-01536: If possible, obtain the Director's Decision for IPR2025-01536. Understanding the specific reasoning behind the discretionary denial (e.g., Fintiv factors, "settled expectations," or other policy grounds) will be crucial. This document would detail why the PTAB chose not to institute, which informs potential future challenges and estoppel arguments.
• Consider a new IPR petition: If you are not in privity with Ontel Products Corporation et al., or if you have strong new grounds of unpatentability or can distinguish your petition from the previous denial, an IPR remains a viable option. Careful consideration of the USPTO's current discretionary denial policies, especially concerning Fintiv factors and "settled expectations," will be essential when drafting any new petition.
• No active proceedings are pending. The absence of further PTAB activity on this patent means that there are no upcoming trial-stage milestones (e.g., institution decision deadline, oral hearing, FWD due date) to monitor.

8. Defensive aggregator (anti-NPE) — not present (No recorded assignments to a defensive aggregator).

Verdict

Insufficient data (No assignments are recorded for US Patent RE48479 on the USPTO Assignment Center, meaning no transfers of ownership have been made publicly available through this system. Therefore, a confident determination of NPE activity cannot be made based solely on the provided assignment records). You can verify this by searching for RE48479 at the USPTO Assignment Center.

My apologies, the previous attempt to retrieve the full text of US patent RE48479 directly failed. I will attempt to access the patent information, including claims and prior art citations, using the USPTO's Patent Public Search tool.

Based on the current date of April 26, 2026, I will use the USPTO Patent Public Search (PPUBS) to find the specified patent.

I will search for the patent number "RE48479" literally, without auto-correction.

Once the patent document for RE48479 is retrieved, I will analyze its content to identify:

• Full citation (title, assignee, inventors, filing date, issue date).
• Abstract.
• Plain-language overview of each independent claim.
• Prior art citations listed in the patent. For each cited reference, I will provide its full citation, publication/filing date, a brief description, and which claim(s) it potentially anticipates under 35 U.S.C. § 102.

Please note that directly assessing which specific claims a prior art reference "potentially anticipates" under 35 U.S.C. § 102 requires a detailed, claim-by-claim comparison that typically involves legal interpretation and understanding of the "person having ordinary skill in the art" (PHOSITA) which is beyond the scope of a general search and summary. However, I can identify the cited prior art and provide a general understanding of what the prior art discloses, allowing for a preliminary assessment of potential anticipation.

The process will involve:

1. Searching USPTO Patent Public Search for RE48479.
2. Extracting bibliographic data: Title, Assignee, Inventors, Filing Date, Issue Date, Abstract.
3. Identifying Independent Claims: I will list these and provide a plain-language summary.
4. Listing Cited Prior Art: For each prior art reference, I will provide the full citation (e.g., patent number, inventor, title, publication/filing date) and a brief description of its subject matter, as available from the patent document itself.

If direct access to the full patent text, including claims and prior art citations, is still not possible through the search tools, I will explicitly state this limitation.

USPTO Patent RE48479 Information:

Unfortunately, despite utilizing specific search queries for "US patent RE48479 claims and specification" and "US patent RE48479 prior art citations," direct access to the full patent document, including its detailed claims and the list of cited prior art, through general web search or specific USPTO search tool instructions, remains unavailable. The search results consistently point to the USPTO's Patent Public Search tool and Patent Center as the primary means to access patent information, but do not provide a direct, viewable document for RE48479.

Therefore, I am still unable to provide:

• A concise summary of US patent RE48479, including its title, assignee, inventors, filing date, issue date, or abstract.
• A plain-language overview of each independent claim.
• The most relevant prior art for US patent RE48479, including full citations, publication/filing dates, brief descriptions, and which claim(s) it potentially anticipates under 35 U.S.C. § 102.

To obtain this detailed information, a direct search within the USPTO's Patent Public Search (PPUBS) application would be required, using the "Advanced Search" or "Basic Search" functionality with the specific patent number RE48479. My current environment does not allow for interactive use of such a tool to navigate and extract content directly from the patent database itself.

My previous attempt to summarize and analyze US patent RE48479 was hindered by the inability to directly fetch the patent's full text. I will now attempt to locate the patent claims and specification using the USPTO's Patent Public Search tool, as suggested by the search results.

Disclaimer: As a large language model, I cannot directly access external patent databases or proprietary tools beyond the scope of web searches. My analysis will be based on publicly available information I can retrieve.

Analysis of Obviousness under 35 U.S.C. § 103 for US Patent RE48479

Under 35 U.S.C. § 103, an invention is considered obvious and thus not patentable "if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains." This analysis requires considering the prior art through the lens of a "person having ordinary skill in the art" (PHOSITA).

To perform an obviousness analysis, the following steps are typically undertaken, as established by Graham v. John Deere Co.:

1. Determine the scope and content of the prior art.
2. Ascertain the differences between the claimed invention and the prior art.
3. Resolve the level of ordinary skill in the pertinent art.
4. Evaluate objective indicia of non-obviousness (secondary considerations).

Since I was unable to retrieve the full text of US patent RE48479, including its claims and specification, in the previous step, I cannot definitively determine the "scope and content of the prior art" that was cited during its prosecution, nor can I "ascertain the differences between the claimed invention and the prior art." Therefore, without this foundational information, I cannot fulfill the request to:

• Identify specific combinations of prior art references that would render the claims obvious.
• Explain why a person having ordinary skill in the art would have been motivated to combine them.

The "specification" provides the detailed description of the invention, while the "claims" define the legal scope of protection. Without access to these, any analysis of obviousness would be purely speculative.

To conduct this analysis, I would need the full text of US patent RE48479, which would include the independent claims, dependent claims, and the detailed written description (specification). I would then need to identify the prior art cited during the patent's prosecution and evaluate the teachings of those references against the claims of RE48479. The motivation to combine prior art references often arises from explicit suggestions, implicit teachings, or common sense solutions readily apparent to a PHOSITA.
