Patent Litigation

  • Regardless of whether a patent practitioner's clients favor a stricter or more lenient eligibility regime, patent eligibility decisions continue to evolve. We need a line drawn for what practitioners expect to be clearer. Hardware inventions are facing patent eligibility challenges that would have seemed more likely in software inventions. Recent court decisions have shown that what once made a hardware invention eligible may no longer fly.

  • Patent marking is an important step in the patent lifecycle as it is generally required to seek damages from infringers prior to the date the suit is filed. While virtual marking has somewhat reduced the overhead of marking, it suffers from the same problems all Internet-based evidence runs into in court: websites are ephemeral and have intermittent accessibility, as well as poor public logging of when information existed where, and for how long. NFTs on a digital blockchain could potentially overcome these hurdles, while still providing the benefits of virtual marking via websites.
