Recapture Rule

The recapture rule is a USPTO doctrine that prohibits a patent owner from using a broadening reissue application to reclaim subject matter that was intentionally surrendered during original prosecution in order to obtain the patent. LEGAL BASIS: 35 U.S.C. § 251; Mentor Corp. v. Coloplast, Inc. (Fed. Cir. 1993); In re Clement (Fed. Cir. 1998) — the leading cases establishing the three-step recapture analysis; POLICY: if an inventor narrows claims to overcome a prior art rejection, the inventor has in effect 'made a deal' with the public — the narrower claims define the scope of the monopoly, and the surrendered subject matter enters the public domain; the recapture rule enforces this bargain, preventing the inventor from getting back through reissue what was given up during prosecution; WHAT TRIGGERS RECAPTURE: (1) the inventor amended claims during prosecution to narrow their scope AND (2) the amendment was made to overcome a rejection AND (3) the reissue claim seeks to broaden the claims back to cover the surrendered subject matter; RECAPTURE IS ABSOLUTE: unlike prosecution history estoppel for DOE (which has Festo exceptions based on tangential relation), the recapture rule is categorical — there are no exceptions once the three elements are established; COMPARE WITH PROSECUTION HISTORY ESTOPPEL: prosecution history estoppel applies in litigation (bars DOE for surrendered subject matter); recapture rule applies in reissue prosecution (bars the broadened reissue claim itself); both ultimately prevent the inventor from reclaiming the same surrendered scope.

Courts and the USPTO apply a three-step analysis to determine whether the recapture rule bars a reissue claim: STEP 1 — IS THE REISSUE CLAIM BROADER THAN THE ORIGINAL CLAIM? A reissue claim is broader if it encompasses subject matter that the original claims did not cover — even if it is also narrower in some limitations; if the reissue claim is narrower than or equal to the original claims in all respects, there is no broadening and the recapture rule is not triggered; STEP 2 — WAS THERE A SURRENDER OF SUBJECT MATTER DURING PROSECUTION? Surrender can occur by: (a) CLAIM AMENDMENT: the applicant amended a claim to add a limitation or delete a broad term to overcome a rejection; (b) ARGUMENT: the applicant made an argument in response to a rejection that expressly or implicitly surrendered scope — even without a claim amendment; the argument must have been relied upon by the examiner to allow the claims; In re Clement: arguments that narrowed claim scope to distinguish prior art can trigger recapture even without formal amendment; STEP 3 — DOES THE REISSUE CLAIM RECAPTURE THE SURRENDERED SUBJECT MATTER? (a) FULL RECAPTURE: the reissue claim covers all of the surrendered subject matter — the most straightforward case; (b) PARTIAL RECAPTURE: the reissue claim covers some but not all of the surrendered subject matter — still barred under In re Clement; PARTIAL RECAPTURE EXCEPTION: if the reissue claim has been 'materially narrowed in other respects' such that it does not cover substantially the same invention as the rejected original claim, it may avoid recapture — but this exception is narrow and requires clear material narrowing in ways unrelated to the surrender.

Recapture and prosecution history estoppel (PHE) both prevent recovering surrendered subject matter, but they operate in different forums and with different consequences: RECAPTURE: (a) applies in USPTO reissue prosecution; (b) results in rejection/non-issuance of the broadened reissue claim; (c) no exceptions — categorical bar once three-step test met; (d) prevents the claim from ever issuing with the broader scope; PROSECUTION HISTORY ESTOPPEL (Festo): (a) applies in district court litigation — used as defense to DOE infringement; (b) does not prevent issuance of broad claims — claims may issue but DOE infringement is barred for surrendered scope; (c) has exceptions (tangential relation, unforeseeable after amendment); (d) applies only to prosecution history surrender for amendment-based prosecution, with more flexibility for argument-based surrender; INTERPLAY BETWEEN THE TWO: if a patent owner narrows claims during prosecution and the patent issues (avoiding recapture issue), prosecution history estoppel then bars DOE claims for the surrendered scope in litigation; if the patent owner tries to get broader claims through reissue, recapture bars this; result: the surrender is doubly enforced — once at the USPTO (recapture) and once in court (PHE); WHAT RECAPTURE PERMITS: a reissue that broadens claims in a direction unrelated to the prosecution surrender does not trigger recapture — the owner is free to broaden in respects unrelated to what was given up; DRAFTING LESSON: if during prosecution you surrender scope you later realize was valuable, and the 2-year broadening reissue window is still open, you CANNOT use reissue to recapture — but you can file a continuation before the parent issues to pursue broader claims not constrained by the prosecution history.

Yes — but the avoidance strategies are limited and depend on the specific prosecution history: (1) BROADEN IN AN UNRELATED DIRECTION: if the reissue claim broadens in a way unrelated to the subject matter that was surrendered, recapture does not apply; example: original claim narrowed by adding a temperature limitation to overcome prior art (surrenders 'any temperature'); reissue claim broadens by expanding pressure range instead of removing the temperature limitation — this is arguably not recapture if the pressure range was not the subject of the surrender; (2) MATERIAL NARROWING IN OTHER RESPECTS: a reissue claim that broadens in the surrendered direction but also adds materially narrowing limitations in other aspects may avoid recapture — but 'material narrowing' must actually narrow the overall scope such that the claim does not cover substantially the same invention as the rejected original claim; (3) FILE CONTINUATION BEFORE ORIGINAL PATENT ISSUES: if you realize during prosecution that you need broader claims, file a continuation application (or CIP) before the parent issues; continuation claims are not constrained by the parent's prosecution history regarding recapture; the continuation can present broad claims not surrendered in the parent's prosecution; (4) CLAIM INDEPENDENT ASPECTS OF THE INVENTION: if the original surrender was limited to one aspect of the invention, reissue can broaden other independent aspects of the invention — parts that were never restricted during prosecution; WHAT NOT TO DO: do not simply remove the narrowing limitation that was added to overcome the rejection — this is textbook recapture; do not argue around the rejection but then try to claim the rejected scope in reissue.

Understanding recapture is essential for effective broadening reissue strategy: AUDIT PROSECUTION HISTORY FIRST: before filing a broadening reissue, conduct a careful prosecution history review — identify every amendment and argument made to overcome rejections; map each narrowing change to the subject matter it surrendered; the reissue claims must not seek to recapture any of this surrendered scope; INDEPENDENT CLAIMS vs. DEPENDENT CLAIMS: even if an independent claim would trigger recapture, the reissue may present new dependent claims that add detail to the original broad independent claims without recapturing surrendered scope — though the independent claim must itself survive recapture scrutiny; ARGUMENTS AS SURRENDER: patent owners often underestimate the scope of prosecution surrenders from argument-based surrender (as opposed to amendment-based); In re Clement: an applicant's argument that the claim required a specific type of structure (to distinguish prior art) surrendered scope even without a formal claim amendment; review arguments carefully; SIMULTANEOUS IPR RISK: if the reissue application is pending when an IPR is filed, the reissue proceeding may be stayed pending IPR outcome; conversely, if the patent owner amends claims in reissue to avoid prior art, those amended claims are subject to reexamination; PROSECUTION TIMING: file the broadening reissue application as early as possible in the 2-year window (ideally immediately after noticing the narrow claim scope at grant) to minimize the time competitors have relied on the original claim scope; EXPECT A RECAPTURE REJECTION: examiners frequently issue recapture rejections even in borderline cases; prepare arguments and claim amendments that address recapture proactively in the reissue application.
