This presentation will discuss recent notable decisions in U.S. litigation of lithium-ion patents, and what those cases can teach us about infringement and invalidity issues in lithium-ion patents. The presentation will focus on the role played by weight/volume claim terms, the duty of disclosure and invention disclosure statements during prosecution, the importance of quantitative examples in lithium-ion patent specifications, and properly presenting prophetic and working examples.

Topics:

  1. Recent notable decisions in U.S. district court and U.S. Patent & Trademark Office (IPRs) litigation of lithium-ion patents
  2. The infringement and invalidity of lithium-ion patent claims:

    • The importance of examples in a lithium-ion patent specification
