Post Grant Review Overview
A new tool was created by the America Invents Act in Section 6 that allows for third parties to challenge issued patents on almost any grounds. This new proceeding is titled “post-grant review” and is formed by the creation of 35 U.S.C. §§ 321-329. Post-grant review works along with inter partes review to replace inter partes reexamination. It is the broadest post-grant validity challenging method at USPTO with the lowest threshold of proof.
- Effective September 16, 2012
- Applies to only AIA patents – filed on or after March 16, 2013
- Post-grant review also applies to those business method patents challenged under the transitional program, no matter when those patents issued.
- Filed by 3P (not patent owner)
- Any basis to challenge patentability – 282(b)(2) or (3): 101, 102, 103, 112 (except best mode)
- This is more broad than for IPR or inter partes reexamination
- TIMING: File within 9 months of patent grant or reissue; after 9 months, you instead file an IPR
- File before petitioner files court action challenging validity
- PETITION must include:
- Fee
- ID real parties in interest
- ID, in writing, and with particularity:
- Each claim challenged
- Grounds for each claim’s challenge
- Evidence supporting each challenge, including copies of patents/printed publications and affidavits/declarations (e.g., expert opinions)
- Any other info the Director requires
- Provide copies of all docs to patent owner or his representative (“serve him”)
- Petition (to the PTAB) will be available to the public
- Preliminary response – patent owner has right to file to argue why no PGR should be instituted
- Filed w/in 3 months
- Can be waived
- No new testimony evidence
- Low threshold to institute – “more likely than not” (preponderance) that at least 1 claim challenged is unpatentable
- PTO will decided whether to institute within 3 months of receiving preliminary response
- PGR will not be instituted if petitioner already filed court action challenging validity of a claim of that patent
- Decision is final and non-appealable
- Reissue – no PGR if: reissue claim is identical or narrower than original patent, AND can no longer file PGR for original patent
- If instituted, PTAB will make decision within 1 year (extendable for good cause by 6 mos)
- Director may consolidate multiple PGRs for a single patent if they are instituted
- Hearing Procedures:
- Conducted in the open (public access) unless sealed (rare)
- Some discovery, and possibility of sanctions
- Amendments by patent owner during IPR – can file 1 motion to:
- cancel challenged claims,
- propose a reasonable number of substitute claims for each challenged one,
- Both parties can agree to change claims to materially advance settlement
- Burden – petitioner must prove unpatentability by a preponderance of the evidence
- Related court proceedings:
- Automatic stay of civil action filed on or after filing of post-grant review
- Counterclaim challenging validity is still allowed in court proceeding
- If you filed in court (DJ), you cannot file PGR – but simply filing invalidity counterclaim does not preclude you filing PGR
- But if civil action within 3 months of patent grant/issue, then court will consider owner’s motion for preliminary injunction
- Estoppel effect – woulda coulda shoulda; petitioner cannot file a civil action or before the ITC or request PTO proceeding on any ground that petitioner “raised or reasonably could have raised” during the PGR
- Automatic stay of civil action filed on or after filing of post-grant review
- Can settle – before PTAB makes decision on merits
- settlement in writing and filed with the USPTO (generally treated as “business confidential info”)
- no more estoppel – petitioner can bring another proceeding
- Intervening rights for amended claims
- Final decision is appealable (by both parties) to courts – but cannot appeal intermediate decisions
- Most foreign countries allow Opposition proceeding – competitors can submit stuff to challenge a published application
Post-Grant Review vs. IPR
- Different eligible patents
- PGR is first 9 months after issue/reissue, while IPR is for after 9 months
- PGR threshold is more likely than not is lower than IPR threshold
