Patent infringement – equivalents 1• Literal infringement – Each & every element of the claims is infringed• Doctrine of equivalents – not literally falling within the scope of the claims <- a somewhat insubstantial feature or element has been replaced – “triple identity” test • It performs substantially the same function • In substantially the same way • To yield substantially the same result Graver Tank & Manufacturing Co. v. Linde Air Products Co. (1950) Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., 535 U.S. 722 (2002) 7 Grace@iii.org.tw & cise.ntut
  • 8. Patent infringement -2• Prosecution history estoppel – makes a change to a patent application to accommodate the requirements of patent law – cannot claim indirect infringement of an element that was narrowed Festo Corp. v.

  • 9. Patent infringement - case study• File wrapper estoppel mixes doctrine of equivalents (04/16/09) – Felix(US6155625) v. American Honda Co. • not literally infringed and estopped from a doctrine of equivalents when the applicant canceled broad claims and incorporated them into dependent claims – The court was testy due to misrepresentations by Felix as to how the dictionary defined the terms “mounted” and “engaging.” » Court: “mounted” as “securely affixed or fastened to” and “engaging” as “forming a seal” » Felix: “bring together” as argued » District court: “latching” – the court noted that Felix rewrote claim 7 , which included “a weather tight gasket mounted on said lip and engaging said lid in its closed position,” into independent form http://www.patentblurb.com/doku.php?id=start 9 Grace@iii.org.tw & cise.ntut
  • 10. Patent infringement - case study (korean)• Korean courts (98 Hur 2160, 1998) set out the following elements in applying the Doctrine of Equivalents explain interchangeability Even if an element is different from that in a patented invention, such element performs the same function in the same way to obtain the same result as the corresponding element of the patented invention known interchangeability the substitute element could have been easily conceived by a person having ordinary skill in the art at the time of the alleged infringement hypothetical claim the alleged infringement is neither the same as nor could be easily conceived from art publicly known prior to the filing date of the patented invention file-wrapper estoppel the substitute element was not excluded from the claims of the patented invention during patent prosecution http://koreanap.co.kr/koreanap_e/sub/property/1_patent.htm 10 Grace@iii.org.tw & cise.ntut
