Sean Patchin, Jr.

I'll research this attorney across the sources before drafting.

Let me verify the tracked cases and the attorney's role in them.

Let me check the IPR outcomes, the ImagineAR case results, and the other two firms in the tracked list.

Professional Summary — Sean Patchin, Jr. (USPTO Reg. No. 77772)

Focus areas. Patchin's practice is prosecution-forward with a litigation component: his Greenberg Traurig profile describes patent preparation and prosecution in the U.S. and abroad, opinions and counseling, diligence, and portfolio management (the firm lists patent prosecution, patent litigation, and portfolio due diligence as his concentrations). The technology areas he advertises track the software/electronics side of the docket — computer networks, cybersecurity, machine learning, augmented and virtual reality, speech and natural language processing, electronic gaming, cloud computing, autonomous vehicles, robotics, and payment processing. His registered-patent work is concentrated in consumer electronics, wireless/remote-control devices, payments, and robotics (e.g., Universal Electronics, Home Depot, PayPal, DataRobot, Chervon, IDEA Industries), and his litigation work to date is AR/location-based mobile gaming. There is no pharma, chemical, or mechanical-heavy portfolio in the sourced record. His B.S. in computer science is consistent with that technical profile.

Side preference. The tracked record is an even 2 plaintiff / 2 defendant, but the verified high-profile work is patent-owner/plaintiff side. He is on the Greenberg Traurig team representing ImagineAR, Inc. as plaintiff in ImagineAR, Inc. v. Niantic, Inc., No. 1:24-cv-1252 (D. Del.), and as patent owner in the parallel Niantic IPRs — the September 2025 correspondence and PTAB filings in those proceedings list him, along with James J. Lukas, Jr., Matthew J. Levinstein, and Benjamin P. Gilford, as Plaintiff/Patent Owner's counsel (Greenberg Traurig was publicly retained by ImagineAR in September 2024 for patent portfolio enforcement). The remaining two tracked appearances — defendant-side local counsel at Potter Anderson & Corroon and plaintiff-side lead counsel at Faegre Drinker Biddle & Reath — are not matched to identifiable case numbers in the data I have, so I can't characterize his role in them or confirm the subject matter. In short: he does not appear to be a career NPE-side specialist, but his verifiable courtroom/PTAB work is on the enforcement side rather than defending operating companies.

Notable matters and PTAB. Public dockets conflict with one tracked entry: a matter captioned in the data as "Unified Patents PTAB Data v. ImagineAR" corresponds in the PTAB record to Niantic, Inc. v. ImagineAR, Inc., IPR2025-01273 through -01276 (filed July 14, 2025, on the '284, '797, '827, and '691 patents). Patchin appears for the patent owner, and the Board denied institution (institution decision January 9, 2026) after ImagineAR pressed § 314(a)/Fintiv discretionary-denial arguments; that is meaningful IPR experience, but it is a single linked family rather than a regular PTAB practice, so I would not describe him as a frequent IPR practitioner. On the district court side, the ImagineAR v. Niantic campaign has gone badly for his client: on September 8, 2025, Judge Wolson granted Niantic's motion to dismiss in part, holding three asserted ImagineAR patents (including the '592 patent) invalid under § 101 and dismissing the pre-suit indirect and willful infringement claims, and an April 7, 2026 opinion treated claim 1 of the '284 patent as representative and found it directed to an abstract idea in connection with Niantic's judgment-on-the-pleadings motion. No verdict, settlement, or Federal Circuit appeal is documented in the sources I could verify. The tracked ImagineAR v. Niantic appearance is attributed in the data to St. Onge Steward Johnston & Reens while the 2025 filings show him at Greenberg Traurig; both firms appear to have been involved in the same matter at different points.

Bar and education. Admitted in Illinois (2021) and Ohio (2020), and registered with the USPTO; J.D., The Ohio State University Moritz College of Law (2020, Assistant Articles Editor, Technology Law Journal); B.S., Computer Science, University of Wisconsin–Madison (2016). Currently an associate at Greenberg Traurig in Chicago. No partner-level title, trial verdict, or published decision appears in the record, and his admission date (2020–2021) means he is early-career — I found no independently verified advocacy results attributable to him personally rather than to his case teams.
