Inter Partes Review (IPR) in a nutshell

Inter partes review (“IPR”) is one of the several tools established under the AIA for an issued patent to be challenged through an administrative process administered by USPTO.  The rationale for using an IPR process rather than a court proceeding is the perceived cost saving even though I personally do not think the process is as inexpensive as the proponents of the AIA have hoped.

Who can initiate an IPR on a patent?
Anyone (other than the patent owner) can initiate an IPR request to cancel one or more claims of an issued patent as unpatentable.  The ground for unpatentability must be the lack of novelty (under 35 U.S.C. § 102) or obviousness (under 35 U.S.C. §103).  The prior art cited for supporting an IPR request can only be patents or printed publications.  This means that you cannot challenge the patentability through an IPR process based on an on-sale bar. 

What kind of patent is subject to an IPR?
You can use IPR process to challenge the patentability of any patent.  For example, you could use the IPR process to challenge your competitor’s patent.  Also, if you are sued for infringement of a patent, you could initiate an IPR process trying to knock the patent out before litigating your case before a court. 

When can you request an IPR on a patent?
You can request an IPR of an issued patent after 9 months following issuance.  However, if the patent is under PGR process, you must wait until the termination of the PGR process before you can file your IPR request.  Also, if you are served with a compliant alleging infringement of the patent, you have one year to request an IPR on the patent.  After one year, you can no longer request an IPR on the patent.  This limitation does not apply to the situation that you are requested to join the litigation.

How do you start an IPR process?
To start an IPR process, you must file a petition under 35 U.S.C. § 311.  The petition must meet the following conditions for the USPTO to consider your IPR request.

First, you must pay a request fee of $9,000.00.  This amount will cover your request for the USPTO to review 20 claims.  If you want to challenge more claims (in excess of 20 claims), you need to pay $200 per additional claim. 

Second, you must identify all real parties in interest.  You cannot be a front for someone else to challenge a patent.

Third, you must identify, in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim.  The evidence may include copies of patents and printed publications that you rely upon in support of the your request.  If you rely on expert opinions, you need to provide affidavits or declarations of supporting evidence and opinions.

Fourth, to put the patent owner on notice that someone is challenging his patent, you must provide copies of the documents required under paragraphs (2), (3), and (4) of 35 U.S.C. § 312(a) to the patent owner or his representative.

Ok, I’ve filed an IPR request on my competitor’s patent.  Then what?
After you filed your IPR request with the USPTO, UPSTO will notify the patent owner that an IPR request has been filed challenging his patent.  The patent owner has the right to file a preliminary response within 3 months of the filing of your request.  In the response, the patent owner will explain to the USPTO why no IPR should be instituted by pointing to the failure of you meeting the above-mentioned requirements.  In this process, you as the IPR petitioner have the burden of proving a proposition of unpatentability by a preponderance of the evidence.

The USPTO will determine whether to institute an IPR within three months after: (1) receiving a preliminary response to the IRP petition; or (2) if no such preliminary response is filed, the last date on which such response may be filed. The standard that the USPTO uses to make the decision is the  “reasonable likelihood that the petitioner will prevail” with respect to at least one of the patent claims.  It is currently understood that the “reasonable likelihood” standard means satisfying a prima facie case of unpatentability.

The USPTO will notify the petitioner and patent owner, in writing, of the Office’s determination of whether to institute IPR, and will make the notice available to the public as soon as is practicable.  The notice will include the date on which the review will start.

If the USPTO grants your request, you will need to pay an additional $14,000 fee for the USPTO to institute the IPR.  This amount will cover 15 claims that will be reviewed by the USPTO.  If you’ve challenged more than 15 claims, you will need to pay $400 for each additional claim.

In addition, if an IPR is instituted, any civil suit filed later or on the same day will be automatically stayed (with some exceptions).

What’s happening during the IPR Proceeding?
During an IPR proceeding, the patent owner may file one motion to amend the patent by: (A) canceling any challenged patent claim; and/or (B) for each challenged claim, proposing a reasonable number of substitute claims.  Additional motions to amend may only be permitted upon the joint request of the IPR requester (the petitioner) and the patent owner to advance materially the settlement of a proceeding.  The patent owner is not allowed to enlarge the scope of the claims of the patent or introduce new matter.

No double dipping: stay and merger
If you file a civil action challenging the validity of any claim of the patent before you file the IPR request on the same patent, your IPR will not be instituted.  If you file the civil action after your IPR request or on the same date of your request, the civil action will be automatically stayed. 

Under this “no double dipping” rule, a counterclaim you filed challenging the validity of a claim of a patent in response to being sued does not constitute “a civil action challenging the validity of a claim of a patent.”

One more thing to keep in mind, during the pendency of an IPR, if another proceeding or matter involving the patent is before the USPTO, the Director has the right to determine the manner in which the IPR or other proceeding or matter may proceed, including providing for stay, transfer, consolidation, or termination of any such matter or proceeding.

No two bits on the apple: Estoppel
So you paid your fee and went through the IPR process.  Now, you received a final written decision from the USPTO Patent Trials and Appeals Board.  But you don’t like the decision.  Can you now go to a civil court (or other administrative places) and try again?  The answer is that depends. 

If you could have “raised or reasonably could have raised” a ground challenging the validity of a patent claim, you cannot use the same ground challenging such patent claim in a district court proceeding, an International Trade Commission (“ITC”) proceeding, or any other USPTO proceeding.  Basically, the decision from an IPR proceeding estops (precludes) your from trying again on the same ground that has already been considered during the IPR proceeding. 

Theoretically, you could try again on a different ground, right?  Well, “reasonably could have raised” covers a lot of grounds.  In practice, you might find it quite hard to get around.

Can I settle during the IPR process?
Before the USPTO has decided the merits of the proceeding, the IPR can be terminated upon the joint request of the petitioner and the patent owner.   If the IPR is terminated, no estoppel will attach—meaning if you settle with the patent owner before the USPTO makes the decision, you are free to challenge the same patent later in a civil court or any administrative proceedings. Any such agreement will be treated as business confidential information, will be kept separate from the file of the involved patents, and will be made available only to Federal Government agencies on written request, or to any person on a showing of good cause.

Thanks for reading.
