Jurisdictional Distinction Between PTAB and Director
Note:
The Board handles appeals related to rejections, while the Director manages petitions concerning objections. Matters determinative of a rejection can be addressed by the Board.

The line of demarcation between appealable matters for the Board and petitionable matters for the Director of the U.S. Patent and Trademark Office (Director) should be carefully observed. The Board will not ordinarily hear a question that should be decided by the Director on petition, and the Director will not ordinarily entertain a petition where the question presented is a matter appealable to the Board. Ordinarily, an objection is petitionable, and a rejection is appealable, but when the objection is "determinative of the rejection" the matter may be addressed by the Board. See In re Hengehold, 440 F.2d 1395, 1403, 169 USPQ 473, 479 (CCPA 1971) and Ex parte Frye, 94 USPQ2d 1072, 1078 (Bd. Pat. App. & Int. 2010)(precedential). Some matters which have been determined to be petitionable and not appealable include: a requirement for restriction or election of species, finality, non-entry of amendments, and holdings of abandonment. As 37 CFR 1.181(f) states that any petition not filed within 2 months from the action complained of may be dismissed as untimely and since 37 CFR 1.144 states that petitions from restriction requirements must be filed no later than appeal, petitionable matters will rarely be present in a case by the time it is before the Board for a decision. In re Watkinson, 900 F.2d 230, 14 USPQ2d 1407 (Fed. Cir. 1990).

Petitions and Appeals Distinction
Note:
The Board will not hear matters that should be decided by the Director, while the Director will not entertain petitions for issues appealable to the Board.

The line of demarcation between appealable matters for the Board and petitionable matters for the Director of the U.S. Patent and Trademark Office (Director) should be carefully observed. The Board will not ordinarily hear a question that should be decided by the Director on petition, and the Director will not ordinarily entertain a petition where the question presented is a matter appealable to the Board. Ordinarily, an objection is petitionable, and a rejection is appealable, but when the objection is "determinative of the rejection" the matter may be addressed by the Board.

Objections Determinative of Rejection Are Appealable
Note:
An objection is typically petitionable, but if it determines the rejection, it becomes appealable to the Board.

The line of demarcation between appealable matters for the Board and petitionable matters for the Director of the U.S. Patent and Trademark Office (Director) should be carefully observed. The Board will not ordinarily hear a question that should be decided by the Director on petition, and the Director will not ordinarily entertain a petition where the question presented is a matter appealable to the Board. Ordinarily, an objection is petitionable, and a rejection is appealable, but when the objection is "determinative of the rejection" the matter may be addressed by the Board.

Petitionable Matters Not Appealable to PTAB
Note:
The Board of Patent Appeals and Interferences will not hear matters that should be decided by the Director on petition, such as objections determinative of rejections or certain procedural requirements.

The line of demarcation between appealable matters for the Board and petitionable matters for the Director of the U.S. Patent and Trademark Office (Director) should be carefully observed. The Board will not ordinarily hear a question that should be decided by the Director on petition, and the Director will not ordinarily entertain a petition where the question presented is a matter appealable to the Board.

Matters Petitionable to the Director, Not Appealable
Note:
Certain patent matters, such as restriction requirements and abandonment decisions, are petitionable to the Director of the USPTO but not appealable to the Board.

The line of demarcation between appealable matters for the Board and petitionable matters for the Director of the U.S. Patent and Trademark Office (Director) should be carefully observed. The Board will not ordinarily hear a question that should be decided by the Director on petition, and the Director will not ordinarily entertain a petition where the question presented is a matter appealable to the Board.

Timely Filing of Petitions Required
Note:
Petitions must be filed within two months from the action complained of to avoid dismissal as untimely, and petitions regarding restriction requirements must be submitted no later than appeal.

Patent Merit Disputes Require Judicial Review
Note:
Disagreements over patentability issues must be resolved through judicial procedures, including appeals to the Patent Trial and Appeal Board or courts.

The United States Patent and Trademark Office (Office) in administering the Patent Laws makes many decisions of a substantive nature which the applicant may feel deny them the patent protection to which they are entitled. The differences of opinion on such matters can be justly resolved only by prescribing and following judicial procedures. Where the differences of opinion concern the denial of patent claims because of prior art or other patentability issues, the questions thereby raised are said to relate to the merits, and appeal procedure within the Office and to the courts has long been provided by statute (35 U.S.C. 134).
