Jonathan Knight is an intellectual property counsel with extensive patent and non-patent litigation and counseling experience. In particular, his patent litigation practice comprises appellate, district court, and ITC cases, including litigation of invalidity and non-infringement positions, analysis of accused products and technical documents, and steering technical expert and source code discovery. He also represents parties in inter partes review proceedings before the Patent Trial and Appeal Board, engaging in all phases of IPR trials, including oral arguments, development of petitions and responses, discovery, RPI briefing and rehearing/POP practice. His work in both litigation and post-grant practice has spanned a broad range of technology fields, including thermal analysis of derailed train cars, polymer chemistry, wind turbine technology, Wi-Fi, content delivery networks, video encoding, video streaming, mobile check deposit systems and light therapy technology.

His patent counseling practice includes intellectual property advice to professional services firms regarding use cases for generative artificial intelligence.  His practice also builds upon his prior experience as a research chemical engineer and finance professional, helping clients procure and exploit proprietary patent positions in artificial intelligence, FinTech, and chemical technologies. His clients have included leading-edge firms focused in artificial intelligence, banking, cybersecurity, blockchain, internet-of-things, pharma, immunoassays, digital health, medical devices, firearm safety and green technology.

His practice includes domestic and international patent procurement, noninfringement opinions, patent validity opinions, IP due diligence, licensing (including analysis of software GPL issues) and business counseling.

Before entering the legal profession, Dr. Knight worked in finance developing proprietary valuation technology for leveraged mortgage arbitrage, heading a team of five PhDs and more than a dozen software, database and network professionals. Dr. Knight founded a firm that deployed capital in asset-backed structured finance (ABS), asset-based loans (ABLs) and private investments in public companies (PIPEs).

Dr. Knight's doctoral thesis integrated computational chemistry tools in mathematical programming-guided design of chemical processes. As a research engineer, he developed a test reactor cooperatively configured with process simulation tools to assess scalability of cationic polymerization catalysts.
