What Casimir Jones does

Casimir Jones, S.C. is a privately-held intellectual property law firm founded in 2007 by Tyler James Sisk (J.D., Ph.D.) and David A. Casimir (J.D., Ph.D.), with Jason R. Bond (J.D.) listed as a third founding shareholder. The firm is headquartered in Middleton, Wisconsin (2275 Deming Way, Suite 310) and operates a remote office in Durham, North Carolina, serving local, national, and international clients. Its core practice areas are Patent Law Services (acquisition, prosecution, enforcement, post-issuance practice, litigation, and infringement opinions across utility and design patents), Trademarks Services (federal, state, and foreign registration, search and analysis, licensing, enforcement, and domain name dispute resolution), and Intellectual Asset Management (portfolio strategy, freedom-to-operate analysis, invalidity and patentability analysis, due diligence, IP licensing, and M&A transaction support). The firm also operates the Casimir Jones Life Sciences Patent Academy, a free educational program introducing diverse candidates to patent law.

The firm's competitive positioning is built on a roster of attorneys with dual J.D./Ph.D. qualifications in life sciences, biotechnology, chemistry, biochemistry, microbiology, and pharmaceuticals, enabling technically rigorous patent prosecution and litigation in complex domains. Notable case outcomes include a $108 million jury verdict in favor of client Raffel Systems, LLC against Man Wah Holdings Ltd. for patent and trade dress infringement, and representation of Promega Corporation in patent infringement litigation against Aobious, Inc. that settled under a consent judgment. The firm serves a horizontal mix of customers including startup companies, Fortune 500 firms with extensive patent portfolios, universities and research institutions, and individual inventors. Pricing is quote-based and not publicly disclosed, consistent with professional services norms, and the go-to-market motion is enterprise field-sales with direct client engagement supplemented by a website intake form.

Revenue mechanics follow a professional services model across three billable service lines (patent, trademark, and intellectual asset management) plus the non-revenue-generating Patent Academy. The firm has no parent company, no disclosed institutional or private equity backing, and no subsidiaries. Thought leadership is a significant brand-building asset, anchored by the AUTM on the Air podcast hosted by shareholder Lisa Mueller (300+ episodes, APEX Award 2024) and the Patent Panorama blog, complemented by active participation in BIO International Convention, AUTM, AIPPI, and government engagement through the White House Council for Inclusive Innovation.
