Renée Mosley Delcollo — Patent Litigation Practice Summary
Specialty and focus. Delcollo is an associate in Greenberg Traurig's Wilmington, Delaware office whose practice centers on intellectual property litigation, with a secondary complex-commercial and employment litigation docket. Her patent work is heavily Delaware-centric and spans several technology and industry verticals rather than a single field: Hatch-Waxman/ANDA pharmaceutical litigation (AbbVie v. Hetero USA, Ingenus v. Accord), medical device and diagnostics (Roche Diabetes Care v. Trividia Health; Ravgen v. Ariosa Diagnostics), robotics/machine vision (RoboticVisionTech v. ABB), solar power electronics (Tigo Energy v. SMA Solar Technology), semiconductor/consumer electronics (DivX v. Realtek), and augmented-reality software (ImagineAR v. Niantic). Firm materials describe her as an IP litigator representing clients in Delaware's state and federal courts, including the Delaware Supreme Court and Court of Chancery, and before state agencies; her Patexia "ANDA Litigation Intelligence Top 100" (2024) listing and Best Lawyers "Ones to Watch" recognition in Litigation–Patent are consistent with that ANDA/Life Sciences tilt.
Side preference. The tracked profile contains a single appearance — one plaintiff-side engagement as local counsel in the Niantic/ImagineAR matter — so no reliable side preference can be drawn from the structured data alone. Broader docket records located through web search show a more balanced local-counsel practice: she has entered appearances for patent defendants (ABB, Hetero, Trividia Health, Mobileum) as well as for patent plaintiffs (Tigo Energy, DivX, Ravgen, ImagineAR). On the current public record, she is best characterized as a full-service Delaware local counsel who takes whichever side the engagement requires, rather than as a dedicated defense-side or NPE-side litigator.
Firm context. Greenberg Traurig, LLP (Wilmington, Delaware), where she is listed as an associate on the IP litigation team. I did not find well-sourced confirmation of prior law-firm employment specific to her patent litigation career; one early docket filing shows a non-Greenberg email address, but I could not verify a prior employer, so no prior-firm history is asserted here.
Notable matters and outcomes. ImagineAR, Inc. v. Niantic, Inc., No. 1:24-cv-01252 (D. Del.), is the tracked case. Delcollo served as Delaware counsel for plaintiff ImagineAR; Niantic filed four IPRs (IPR2025-01273–01276) against the asserted patents and stipulated to Sotera-style estoppel. In April 2026, the court granted Niantic's motion for judgment on the pleadings and entered final judgment for Niantic, holding four asserted patents (U.S. Patent Nos. 10,946,284; 11,484,797; 11,666,827; and 12,070,691) invalid under 35 U.S.C. § 101 — a loss for her client. On the other side of the "v." she appears for defendants in AbbVie Inc. v. Hetero USA, Inc. (ANDA) and RoboticVisionTech, Inc. v. ABB Inc., and for plaintiff Tigo Energy in Tigo Energy Inc. v. SMA Solar Technology America LLC, where she and colleagues were noted in Law360 coverage after the court declined to stay the case ("Solar Energy Co. Can't Shut Down Rival's Patent Suit," Oct. 2023). Ravgen v. Ariosa Diagnostics and DivX v. Realtek are additional tracked-docket matters in which she appeared before her 2022 withdrawal.
PTAB / IPR experience. Her PTAB exposure is as Delaware district-court counsel in matters running parallel to instituted or filed IPRs, not as a first-chair petitioner's counsel of record. She is named in PTAB correspondence for the Niantic IPRs (Niantic, Inc. v. ImagineAR, Inc., IPR2025-01273–01276) as district counsel for the patent owner, and her Trividia Health engagement ran alongside IPR2025-00553. No evidence found of her independently authoring IPR petitions or arguing before the Board.
Bar and education. Admitted in Delaware and the U.S. District Court for the District of Delaware (Delaware bar since 2016); J.D., magna cum laude, Widener University Delaware Law School (2016); B.A., The Catholic University of America.
