Dennis C. Bremer

Dennis C. Bremer — Patent Litigation Practice Summary

Specialty / focus. Bremer is an IP litigator whose practice centers on patent and trade secret litigation, plus infringement/validity opinions and licensing work (Carlson Caspers firm bio). He holds a B.S.E.E. from Duke and leans on an electrical engineering/computer science background, but his matters span magnetics, semiconductors, telecommunications, aerospace, pharmaceuticals, mechanical, agriculture, and automotive technology. The tracked matter in the profile is a plaintiff-side case where he served as lead counsel; the untitled case cannot be named from available records, so no case-specific technology details are confirmed.

Side preference / firm context. The tracked docket shows one plaintiff-side appearance (lead counsel) — a profile too small to infer a systemic preference. His verifiable broader practice runs both sides: he has prosecuted infringement claims for patent owners (Polaris, Spectralytics, Anchor Wall) and defended petitioners in IPRs (CommScope). He has spent his entire patent career at Carlson Caspers Vandenburgh & Lindquist in Minneapolis (formerly Carlson Caspers Vandenburgh Lindquist & Schuman), where he has practiced roughly 25–30 years, and he clerked for Judge Frank Magill on the Eighth Circuit early on.

Notable cases / outcomes. Bremer was part of the Carlson Caspers teams that won two significant Minnesota jury verdicts for small patent owners: Spectralytics v. Cordis (D. Minn. 2009, $22.35M verdict on a stent-manufacturing method patent) and Anchor Wall Systems v. Rockwood Retaining Walls ($30M damages verdict on retaining-wall block patents, after a decade of litigation). He also represented Polaris in Polaris v. Arctic Cat (D. Minn.) over side-by-side ATV patents and served as lead counsel for Polaris as patent owner in IPR2017-00433 defending the '501 patent.

PTAB/IPR experience. Bremer appears regularly before the PTAB in both roles — lead counsel for patent owner Polaris (IPR2017-00433), backup counsel for patent owner Teleflex (IPR2020-00136) and for petitioner CommScope against Belden (IPR2023-01056, -01061, -01062), and in the DAI/M-I Drilling IPR series (IPR2016-00256 et seq.).

Bar / education. J.D., Washington University School of Law (1994, Order of the Coif); B.S.E.E., Duke University (cum laude). Admitted in Minnesota, Missouri, and Illinois; before the Federal and Eighth Circuits; registered with the USPTO (Reg. No. 40,528). (Note: some directories list a 2003 J.D., but the firm bio and Martindale confirm 1994.)
