David P. Berten

I'll research this attorney's background before drafting.

Let me gather more on specific cases and PTAB activity.

Overview. David P. Berten is a Chicago-based patent litigator and the founder of Global IP Law Group, LLC. His practice is unusually technology-agnostic: press profiles describe him handling matters spanning chemical and thermal-barrier coatings, genetics, vehicle navigation systems, semiconductors, medical devices, machine vision and barcode systems, and digital communications software. His more recent docket activity clusters around software, e-commerce, wireless/mobile-device functionality, and color-imaging/graphics patents. Beyond litigation, a substantial part of his practice is patent monetization — valuation, licensing, and portfolio sales — often on contingency.

Side preference. He works essentially exclusively for patent owners and monetization vehicles. The tracked case list shows 1 plaintiff-side appearance and 0 defendant-side appearances, and his broader verified docket is consistent: he has represented plaintiffs including Disintermediation Services, Inc., Ironworks Patents LLC, RAH Color Technologies LLC, Rich Media Club LLC, and Biogy, Inc. He does not appear to defend operating companies against infringement claims. His firm's model is explicitly to combine selling, licensing, and enforcement for patent holders.

Firm context. Berten founded Global IP Law Group in March 2009 with Steven Steger (previously chief IP counsel at Ygomi). Before that he was an associate at Kirkland & Ellis (1989–1993), a partner at Bartlit Beck Herman Palenchar & Scott (1993–1998), and founder/partner at Competition Law Group (1999–2009). His commercial reputation rests heavily on Global IP's role advising bankrupt Nortel Networks on the $4.5 billion sale of its ~6,000-patent portfolio to the Rockstar consortium in 2011, and on its advisory work for unsecured creditors in the Kodak bankruptcy patent sale.

Notable matters. The tracked case is Disintermediation Services, Inc. v. Living Spaces Furniture, LLC (E.D. Tex., No. 2:24-cv-01045, filed Dec. 2024, before Judge Gilstrap), a willful-infringement suit asserting four patents on two-way real-time communication. Search-verified additional matters include the Ironworks Patents campaigns against Samsung (N.D. Cal.) and Motorola Mobility (N.D. Ill.), in which the Federal Circuit vacated and remanded claim-construction rulings on the ’078 and ’239 patents (Ironworks Patents LLC v. Samsung Elecs. Co., No. 20-1191, nonprecedential, Feb. 2020); the RAH Color Technologies v. Adobe multidistrict litigation (N.D. Cal.), resolved by stipulated dismissal in 2021; and Rich Media Club LLC v. Duration Media LLC (D. Ariz.), which was stayed pending IPR and later went up on appeal. Reported outcomes in these matters are mixed and largely non-final, so I would not characterize any as a verified win.

PTAB/IPR. Berten appears regularly as patent-owner counsel in PTAB proceedings. Documented examples include the four Adobe Inc. v. RAH Color Technologies LLC IPRs (IPR2019-00627, -00628, -00629, -00646), where he handled real-party-in-interest discovery and witness cross-examination, and Motorola Mobility LLC v. Ironworks Patents LLC (IPR2021-00420/-00421). He also represented Rich Media Club in IPR2024-00937, where the Board denied institution.

Bar and education. Admitted to the Illinois bar in 1989 (IL Bar No. 6200898); also admitted to the U.S. Supreme Court and the Third, Seventh, and Federal Circuits. J.D., cum laude, University of Wisconsin Law School (1989); B.C.P. in urban planning, University of Virginia School of Architecture.

Caveat: the tracked appearance list contains only one case and likely understates his docket; the additional matters above come from court filings, PTAB records, and press reporting rather than the tracked dataset.
