Advanced Patent Prosecution Workshop: Claim Drafting & Amendment Writing

Yesterday, I attended PLI’s Advanced Patent Prosecution Workshop 2011 in New York where an esteemed panel of experts offered hands-on claim drafting and amendment writing techniques.  The program was organized into four technological sections: Biotechnology, Chemical/Pharmaceutical, Electrochemical and Electronics/Computers. I attended the Chemical/Pharmaceutical segment whereJohn Todaro of Merck & Co. discussed advanced issues in drafting of patent specifications.

Here are some highlights from his presentation….

-Draft the claims or Summary of the Invention first, because of the primary role of the patent specification in claim construction

-General Considerations in Drafting the Specification:

1. Distinguish invention from the prior art
2. Define claim terms
3. Provide broadest possible claim scope, while complying with section112 requirements
4. Consider ex-US patent law issues

–Control the length of the application – too long = excess fees. Cost issue is important, think about when drafting the application. (more…)

BILSKI: Where Do We Go From Here?

The following guest post comes from  Kenneth Nigon, Practice Manager for the Patent Preparation and Prosecution Group at RatnerPrestia and PLI Faculty member.

On Tuesday, July 27, the USPTO published its Interim Guidance for Determining Subject Matter Eligibility for Process Claims in view of Bilski v. Kappos (“Interim Bilski Guidance”).  This Guidance supplements the Interim Examination Instructions for Evaluating Subject Matter Eligibility Under 35 U.S.C. § 101 (“Interim Instructions”), published on August 24, 2009 and the memorandum to the Patent Examining Corps on the Supreme Court Decision in Bilski v Kappos published on June 28, 2010 (“Bilski Memorandum”).

The Bilski Memorandum instructs the examiners to reject method claims that do not meet the requirements of the Machine or Transformation (MoT) test formulated by the Federal Circuit in In re Bilski 545 F.3d 943 (Fed. Cir. 2008).  The Interim Bilski Guidance modifies these instructions to require examiners to apply a balancing test which weighs factors both in favor of and opposed to patent eligibility and directs examiners to consider all requirements for patentability in the interest of compact prosecution.

The factors weighing in favor of eligibility of a claim include that it:

• passes the MoT test,
• is directed toward the application of a law of nature and
• is more than a mere statement of a concept. (more…)
