​Matt Gavronski is a founding member of the Hansen Reynolds Patent Prosecution practice group. With over two decades of patent experience, Mr. Gavronski has helped clients large and small protect their innovations while simultaneously navigating the minefields of competitor patent rights. Prior to joining the firm, Mr. Gavronski practiced patent law with Michael Best & Friedrich and McDermott Will & Emery before moving in-house to Clover Environmental Solutions, a global leader in printer cartridge remanufacturing and returns management. At Clover, Mr. Gavronski built and managed an in-house patent practice while serving in the roles of Chief IP Counsel and General Counsel. Drawing from his diverse background, Mr. Gavronski provides practical, pragmatic, and actionable advice tailored to the specific needs of each client.


Designed, implemented, and oversaw in-house product development processes incorporating patent prosecution and patent clearance methodologies, resulting in a ten-fold increase in patent holdings and a 10-year (and counting) run of no adverse infringement claims in the competitive and extremely litigious printing supplies industry.

Intimately familiar with the legal issues and regulatory challenges associated with circular economic business models and third-party product remanufacturing. Subject matter expert in the fields of patent exhaustion and permissible repair.

Initiated and led meetings with U.S. Customs and Border Protection to ensure continued availability of critical outsourced components in response to issuance of General Exclusion Orders by the International Trade Commission.

Successfully devised and executed multi-prong international invalidity proceedings against a client competitor’s patent portfolio, leading to the successful invalidation of the competitor’s U.S. and European patents and permitting the client to enter a previously foreclosed global market worth more than $500MM.
