Patentability classification search

  1. 1. Patentability search – 1 (classification search) Chen JingFung (Grace) 2012/05/03Chapter 6, “Patent It Yourself: Your Step-by-Step Guide” 15th, 2011, ISBN: 1413313825
  2. 2. outline• Why make a Patentability Search? – Counter example against ordinary skills – Define the scope & Dig novel features• Patent infringement• Patent search – classification search – Espacenet, USPTO.. – USPTO check patent application status & cise.ntut 2
  3. 3. Why make a Patentability Search? Check grant patents on your invention? Learn valuable background info. Avoid wasting time/ moneyInvention in what field? “feel for the art”• Valuable background info – Know how to describe & draw components • Contain a detailed description of your invention • Provide more info about operability & design • Obtain commercial info 3 & cise.ntut

  5. 5. Counter example against ordinary skills• cited some uncover references to help convince the examiner – Show that you’ve turned a past failure into success – “+ proof “ that your invention provides unexpected results & is unobvious Look Fog as reading a Light-emitting Glossy/ paper devices stimulate flash the mind resulting in poorer sleep (ref: Oska University, Fig ref: Kreative Discussions 5 & cise.ntut
  6. 6. Define the scope & Dig novel features• Define the general thrust, structure & advantage of your patent application LeRoy invented a sturdy but edible, baked scoop for dips, including sala similarity advantage LeRoy vs. Minerva’s cereal LeRoy’s is more stable shape product than Minerva’s• After searching, you’ll be able to recited, pointed out novel features & advantage on your patent application – Tailor your claims to such novel features • Avoid the need to narrow your claims & cise.ntut 6
  7. 7. 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 & cise.ntut
  8. 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. Shoketsu Kinzoku Kogyo Kabushiki Co., 535 U.S. 722 (2002) & cise.ntut 8
  9. 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 9 & cise.ntut
  10. 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 10 & cise.ntut

  12. 12. Patent search - classification search• Classification search – make a search of all patents in a particular class and subclass – EPO and USPTO work toward joint classification system • Develop a joint classification system (CPC) based on the European Classification system (ECLA) – Improving patent searching ECLA USPC IPC CPC EPO USPTO WIPO – Sharing resources » shared in order to classify documents, to revise the scheme when necessary and to subsequently reclassify documents 12 & cise.ntut
