Prosecution ProcessSearch Fee and Examination Fee are paid along with Filing Fee in USPTO. So the Examination starts automatically after the non-provisional patent application is filed. Examination may be expedited under Patent Prosecution Highway (PPH).   Non-Final Office Action is issued after the Examination is completed. Response must be filed within 3 months from the date of issuance of the Non-Final Office Action.  If the Examiner is not satisfied with the response submitted to the Non-Final Office Action he will issue a Final Office and then a Non-Final Office Action and so on.   The time period of 3 months to respond to an Office Action can be extended for a further period of 3 months by filing a request for extension of time. A response to Office Action filed during the extended period should be accompanied by a Request for Continued Examination.   If the Examiner is satisfied with the response, application will proceed to acceptance and then registration.   After the Notice of Allowance is issued, there is a 3 months’ time period to pay the Issue Fee. After the issued fee is paid the USPTO issues the Patent Certificate.   USPTO also requires the submission of Information Disclosure Statement (IDS) before the issuance of Office Action. IDS if submitted after the issuance of Office Action, the same needs to be submitted with an Official Fee. It is generally recommended to always submit IDS with USPTO.

A maintenance fee paid on the last day of a window period can be paid without surcharge. The last day of a window period is the same day of the month the patent was granted 3 years and 6 months, 7 years and 6 months, or 11 years and 6 months after grant of the patent.

Post Grant Review

Post grant review is a trial proceeding conducted at the Board to review the patentability of one or more claims in a patent on any ground that could be raised under § 282(b)(2) or (3). Post grant review process begins with a third party filing a petition on or prior to the date that is 9 months after the grant of the patent or issuance of a reissue patent. The patent owner may file a preliminary response to the petition. A post grant review may be instituted upon a showing that, it is more likely than not that at least one claim challenged is unpatentable. If the proceeding is instituted and not dismissed, a final determination by the Board will be issued within 1 year (extendable for good cause by 6 months). The procedure for conducting post grant review took effect on September 16, 2012, and generally applies to patents issuing from applications subject to first-inventor-to-file provisions of the AIA.

The grounds that could be raised are as follows:

  1. Invalidity of the patent or any claim in suit on any ground specified in part II  of this title as a condition for patentability,
  2. Invalidity of the patent or any claim in suit for failure to comply with—

(A) any requirement of section 112, except that the failure to disclose the best mode shall not be a basis on which any claim of a patent may be canceled or held invalid or otherwise unenforceable; or (B) any requirement of Section 251.
