Patent Reexamination Search USPTO Program
Challenge a granted patent on the strength of what the examiner never saw. Rights Reality delivers focused prior art searches for ex parte reexamination — built to raise a substantial new question of patentability and to withstand scrutiny.
What is a Patent Reexamination Search?
A reexamination search is the prior art work that underpins a request for ex parte reexamination — the USPTO procedure through which a granted patent's claims are examined afresh in light of art the office did not properly consider the first time. Rights Reality conducts these searches with one clear target in mind: finding references strong enough, and new enough, to raise a substantial new question of patentability.
This is not a general invalidity search, and treating it as one is a costly mistake. Reexamination rests on patents and printed publications only, and the art must be genuinely new — references the examiner already weighed, or that merely repeat what was weighed, will not carry a request. Our team maps the prosecution history first, so we know precisely what the office has already seen, and then search for what lies beyond it.
Substantial New Question
Art targeted specifically to clear the SNQ threshold.
No IPR Estoppel
Reexamination does not trigger § 315(e) estoppel.
Cost-Effective Route
A far lighter spend than a full PTAB proceeding.
Why Choose Reexamination?
Ex parte reexamination has become the leading first-stage validity tool at the USPTO. Here is why clients choose this route — and why they choose us for the search.
-
A merits-based threshold — Reexamination turns on the substantial new question standard, not on the discretionary factors now shaping PTAB institution.
-
No IPR estoppel — Unlike an unsuccessful IPR, reexamination does not bar you from raising invalidity grounds later in district court.
-
Substantially lower cost — A fraction of the expense of a full inter partes proceeding, which matters when validity is one front of a wider dispute.
-
Support for a litigation stay — A pending reexamination can strengthen a motion to stay district court proceedings.
-
New art, properly identified — Our search is built around what the examiner has not seen, because that distinction is what the entire request depends on.
