# Give up the claims, and the review never starts.

In two 2017 rulings, precedential (Skky as to § II.B.2 only), patent owners disclaimed challenged claims before the Board decided whether to institute. The Board treated those claims as if they had never existed: no review of them, and no ruling on whether the petitioner was right.

**17 of 17** challenged claims disclaimed in GE v. United Technologies. No review was instituted.

## Before you read

Before the institution decision, the owner disclaims every challenged claim but says it still disagrees with the petition. What happens?

- The Board decides the merits anyway
- No review is instituted
- The disagreement keeps the claims alive

No review is instituted. Under 37 C.F.R. § 42.107(e), no inter partes review will be instituted based on disclaimed claims, and in GE every challenged claim had been disclaimed.

## Seventeen claims, gone

GE challenged all 17 claims of a patent owned by United Technologies and MTU Aero Engines. The owners said they “strongly disagree[d]” with GE’s unpatentability arguments, then disclaimed all 17 claims anyway. GE, pp. 2–3

The Board checked the two disclaimer filings against Office records and found the disclaimer of claims 1 to 17 recorded as of April 12, 2017. Because “all claims challenged by GE have been disclaimed,” it ordered “that no inter partes review is instituted for any claim challenged by GE.” The decision never reaches the prior art. GE

## What a disclaimer is

A statutory disclaimer is a filing in which the patent owner permanently gives up one or more claims. Once recorded, it is “considered as part of the original patent.” 35 U.S.C. § 253(a) The PTAB’s rules let an owner file one before institution, and state the effect: “[n]o inter partes review will be instituted based on disclaimed claims.” 37 C.F.R. § 42.107(e)

## Disclaim some, change the question

Skky used a disclaimer differently. Facebook petitioned for covered-business-method review of claims 1 to 11 of a Skky patent. That program was available only for patents that qualified as covered business method patents. The day before its preliminary response, Skky disclaimed claims 6 and 8 to 11, and argued the rest didn’t qualify. Facebook v. Skky

The panel agreed and denied institution. Facebook sought rehearing, and the panel was expanded. It held that eligibility “is determined based on the claims of the challenged patent as they exist at the time of the decision whether to institute, and statutorily disclaimed claims must be treated as if they never existed.” It rejected fixing eligibility at the date the petition was filed, and denied rehearing on September 28, 2017. Facebook v. Skky

The covered-business-method program expired on September 16, 2020. The principle carries over: what counts at institution is the patent as it stands then, not as it stood when the petition was filed.

## Price the surrender

A docket entry that says “not instituted” leaves out the event that matters commercially: the owner gave up the claims.

For a petitioner trying to remove exposure under specific claims, the surrender may achieve the goal without a trial. For an owner, it may be a sensible way to stop spending on rights no longer worth defending. Neither conclusion follows from the status entry alone.

## What to do

Choose your side.

## Cuts the other way

Both are 2017 Board decisions, precedential (Skky as to § II.B.2 only) but not court rulings, and Skky concerns a program that no longer exists. A disclaimer also ends review only of the claims it covers. An owner that disclaims some claims still faces review of the rest.

Whether a disclaimer before institution has other consequences for the owner, such as under the adverse-judgment rule, is not addressed in these decisions and has not been researched for this story.

## The takeaway

Describe the result to the client as rights surrendered, not just a proceeding avoided. That is the decision they are making.

## Not yet confirmed

- Whether a disclaimer before institution has other consequences for the owner, such as under the adverse-judgment rule, is not addressed in these decisions and has not been researched for this story.

Each item is marked in the story with a dashed outline. We update the story when the official record confirms or corrects it.

Precedential decisions bind the Board within their designated scope. Informative decisions show the Office’s reasoning but do not bind the Board. Court opinions are cited for what they decided; later history was checked on the date shown above.

Updated

- October 17, 2026: Skky is precedential only as to § II.B.2, as the USPTO list shows. The summary and the limits section now say so.
