Case overview & background
Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.
The IPR case IPR2022-01356, Unified Patents v. CONSUMERON LLC, involves a challenge to US Patent 8,244,594 at the Patent Trial and Appeal Board (PTAB). Unified Patents is a member-based organization dedicated to deterring unsubstantiated or invalid patent assertions by Non-Practicing Entities (NPEs) and improving patent quality across various technology sectors. They achieve this by monitoring NPE activity, conducting patent analytics, and directly challenging the validity of patents, often through Inter Partes Reviews. CONSUMERON LLC, the patent owner, has been identified as a patent-holding entity (NPE) that asserts rights over e-commerce delivery technology, focusing on intellectual property monetization. Its president and CEO, Mark B. Barron, is also a named inventor on some of its patents.
The patent at issue, US Patent 8,244,594, titled "System and method for remote acquisition and delivery of goods," generally relates to e-commerce logistics and consumer delivery platforms. This technology covers foundational processes in consumer-facing delivery workflows, making it broadly applicable in sectors like online grocery and retail delivery. This IPR is part of a broader pattern where Unified Patents challenges patents asserted by NPEs, particularly those related to widely used technologies, to reduce the risk of costly patent litigation for its members.
The procedural posture of this case is an Inter Partes Review (IPR) before the Patent Trial and Appeal Board (PTAB), a branch of the United States Patent and Trademark Office (USPTO). The case is currently at the "Final Written Decision" stage, indicating that the PTAB has issued a conclusive ruling on the patentability of the challenged claims. PTAB proceedings offer an alternative avenue to district court litigation for challenging patent validity, often favored for being a more streamlined and cost-effective process. The notability of this case stems from Unified Patents' consistent strategy of targeting patents held by NPEs in high-activity technology zones. This particular patent (US Patent 8,244,594), along with related patents in CONSUMERON's portfolio, has also been asserted in district court litigation, notably against Instacart (Maplebear, Inc.), where some of CONSUMERON's patents covering similar "remote acquisition and delivery of goods" were found invalid under 35 U.S.C. § 101 for being directed to patent-ineligible subject matter. This IPR, therefore, fits into a larger context of challenges to business method and e-commerce patents, which often face scrutiny under patent eligibility standards (e.g., Alice Corp. v. CLS Bank International). The PTAB's decision on this patent contributes to the ongoing discourse regarding patentability in the e-commerce delivery technology space.
Key legal developments & outcome
Major rulings, motions, claim construction, settlements, and the present posture or final disposition.
Unified Patents successfully challenged the validity of U.S. Patent No. 8,244,594 B2, owned by CONSUMERON LLC, through an Inter Partes Review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB). The PTAB's decision to invalidate the patent was ultimately affirmed by the U.S. Court of Appeals for the Federal Circuit.
Here's a chronological breakdown of the key legal developments and outcome:
- IPR Filing: Unified Patents filed a petition for Inter Partes Review, IPR2022-01356, challenging U.S. Patent No. 8,244,594. The specific filing date for IPR2022-01356 is not explicitly present in the provided search results but is generally found in IPR proceedings leading to appeals in 2024.
- Institution Decision: The PTAB likely instituted the IPR after reviewing the petition and any preliminary response from CONSUMERON LLC. The search results confirm that the Federal Circuit appeal stemmed from PTAB decisions in IPR2022-01356, along with IPR2022-01357, IPR2022-01358, and IPR2022-01359, indicating institution occurred for these proceedings. The precise date of institution for IPR2022-01356 is not in the provided information.
- Final Written Decision (FWD): The Patent Trial and Appeal Board issued a Final Written Decision in IPR2022-01356 (and the related IPRs), finding claims of U.S. Patent No. 8,244,594 B2 unpatentable. The specific date of the FWD from the PTAB is not provided in the search results, but it occurred prior to the Federal Circuit appeal.
- Federal Circuit Appeal: CONSUMERON LLC appealed the PTAB's Final Written Decision to the U.S. Court of Appeals for the Federal Circuit. The appeal, consolidated under case numbers 24-1703, 24-1704, 24-1705, and 24-1706, was filed on April 17, 2024. The case was captioned "Consumeron, LLC v. Maplebear Inc., dba Instacart" at the Federal Circuit, indicating Maplebear (Instacart) was likely an interested party or had a parallel challenge.
- Federal Circuit Affirmance: On January 12, 2026, the Federal Circuit affirmed the PTAB's invalidity ruling in a nonprecedential per curiam judgment under Rule 36. The panel included Circuit Judges Dyk, Stoll, and Cunningham.
- Outcome: The Federal Circuit's affirmance resulted in the invalidity and cancellation of U.S. Patent No. 8,244,594 B2. This means CONSUMERON LLC was left without enforceable patent rights for this patent. The appeal was resolved on patentability grounds, specifically through an invalidity and cancellation action, consistent with challenges under 35 U.S.C. §§ 102 (anticipation) or 103 (obviousness).
Plaintiff representatives
Counsel of record for the plaintiff(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).
I could not identify the specific counsel of record representing Unified Patents in IPR2022-01356 from the publicly available search results. While Unified Patents often utilizes a combination of in-house counsel and various external law firms for its inter partes review (IPR) proceedings, the precise attorneys and their firms for this specific case (IPR2022-01356 against CONSUMERON LLC concerning US patent 8244594) were not explicitly listed in the provided snippets from PTAB analytics, news articles, or other legal databases.
Information on Unified Patents' legal representation in other IPRs indicates they work with firms such as Rothwell, Figg, Ernst & Manbeck, P.C. (e.g., in IPR2022-00002) and also employ in-house counsel like Jonathan Stroud, Michelle Aspen, and David C. Seastrunk, who are often listed as back-up counsel or general counsel for the organization. However, these are general or case-specific to other IPRs and do not directly apply to IPR2022-01356.
To definitively identify the counsel of record for IPR2022-01356, access to the official PTAB docket for this case, or the full text of its Final Written Decision or the associated Order Denying Director Review, would be necessary.

- Stevens & Lee
- Michael B. Eisenberg · Lead Counsel
- O'Connell Law Office
- Thomas P. O'Connell · local counsel
In the IPR2022-01356 case, Unified Patents v. CONSUMERON LLC, the counsel of record for defendant CONSUMERON LLC appears to include:
Michael B. Eisenberg - Lead Counsel
- Firm: Stevens & Lee, with offices in New York and Princeton, NJ.
- Experience: Mr. Eisenberg is a shareholder at Stevens & Lee and focuses on intellectual property litigation, including patent, copyright, and trade secret matters, in district and appellate courts. He has particular experience with IP litigation issues in solid-state lighting, software, solid-state memory, camera sensors, and semiconductor processing. He also routinely provides counsel on the use of Inter Partes Reviews (IPRs) as part of litigation and settlement strategy, having served as counsel in technology-related IPRs on behalf of both patent owners and defendants. He maintains an active appellate practice before the U.S. Court of Appeals for the Federal Circuit and previously served as a Law Clerk to the Hon. Timothy B. Dyk of the Federal Circuit.
Thomas P. O'Connell - It is highly probable he serves as "Of Counsel" or "Local Counsel."
- Firm: O'Connell Law Office, located in Arlington, Massachusetts.
- Experience: Thomas P. O'Connell is a Registered Patent Attorney with over twenty-five years of experience representing individual and corporate clients. He has a Bachelor of Science degree in Mechanical Engineering. His firm handles intellectual property protection and enforcement, prosecuting hundreds of patents and providing litigation services in federal and state courts across the U.S. He also acts as local counsel in the U.S. District Court in Boston. Notably, he has experience prevailing in trials (bench and jury) and arbitrations, including a $2.4 million verdict for willful patent infringement.
While other attorneys named "Jeffrey O'Connell" appear in search results, their listed experience and firm affiliations (e.g., toxic tort litigation at Nemeroff Law Firm or corporate law in Oakland, CA) do not align with patent litigation for CONSUMERON LLC or with the IPR case. Therefore, Thomas P. O'Connell is the more relevant match given the firm's specific focus on intellectual property and patent litigation.
