CLS Bank, numerous patent eligibility cases have flooded district courts, the Federal Circuit and impacted practice before the U.S. Patent Trademark Office (USPTO). Over the coming weeks and months, patent practitioners and industry anticipate a continuing number of significant patent eligibility decisions that will further reshape and remodel the landscape of patent eligibility law.

  • The fast changing Intellectual Property (IP) landscape creates a more complex environment for companies to cope up with. Such complexity creates numerous challenges on how companies handle their intellectual capital assets and to ensure that they would produce a sustainable competitive advantage over their competitors.  Mr. Hudnell participated on a panel of key thought leaders to present their findings and best practices that would be able to adopt to the Changing Landscape of Intellectual Property Strategies., Speaker, The Changing Landscape of Intellectual Property Strategies: What Every Firm Needs to Know, The Knowledge Group Live Webcast, 2015
  • In following the U.S. Supreme Court’s decision in Alice Corp. v. CLS Bank International, patent owners and applicants must acknowledge the change brought about by the Alice case.

  • Presented on best practices and resources for law firm management and operations, case management, marketing and business development, and other aspects of running a minority-owned firm in today’s market., Speaker, Strategies and Tools for Minority-Owned Law Firm Success, California Minority Counsel Program, 2017
  • Although the U.S. Supreme Court’s decision in Alice Corp. v. CLS Bank Int’l set forth a two-part test for determining patent eligibility, both the Supreme Court and the Federal Circuit have drawn on other sections of the patent statute to determine eligibility. As a result, in many instances, patent-eligibility determinations have resembled patentability determinations. By blending different inquiries under the patent statute, Alice and its progeny have made determining what constitutes patent-eligible subject matter unclear and arguably made the patent system weaker., Author, The Post-Alice Blend Of Eligibility And Patentability, Law360, 2017
  • In the later part of 2017, the U.S. Court of Appeals for the Federal Circuit  made clear that the Supreme Court’s decision in TC Heartland v. Kraft Foods dramatically changed the patent venue landscape. An alleged infringer may now argue improper venue “in a judicial district where it is subject to a court’s personal jurisdiction but where it is not incorporated and has no regular and established place of business.” As a result of this Federal Circuit opinion and many other post-TC Heartland decisions, venue is becoming a much more complicated issue.  Mr. Hudnell particpated in a panel of key thought leaders they delve into an in-depth analysis of the current trends and recent court rulings involving determination of Patent Venue in light of the TC Heartland decision. , Speaker, Determining Patent Venue in the Light of TC Heartland Decision, The Knowledge Group Live Webcast, 2018
  • For the first three years following the Supreme Court issued its landmark decision in Alice Corp. Pty. Ltd. v. CLS Bank Int’l. , the U.S. Court of Appeals for the Federal Circuit had overwhelming ruled against the patent owner on eligibility challenges. Many have argued that the risk of having a patent declared ineligible under Alice has discouraged investments in innovation, particularly for software companies, and weakened the U.S. patent system. But a recent string of Federal Circuit decisions in favor of patent owners, all issued in 2018, may provide new hope for patent owners and restore balance to the patent-eligibility landscape.  Mr. Hudnell participated in a discussion analyzing the recent developments surrounding this important topic and provided practical insight for in-house decision makers on the impact of these significant developments., Speaker, From Wonderland Back to Reality: A Practical Look at the Recent Changes in Patent-eligibility Jurisprudence, Select Counsel In-House Focus Presentation, 2018
