Protestor Cannot Submit Additional Protests on Same Issues
Note:
A protestor cannot submit additional protests with the same real party in interest for the same application, except under specific conditions outlined in 37 CFR 1.291(c)(5).
Under 37 CFR 1.291(d), protestor participation ends with the filing of the protest, and protestor will not be allowed to complete any protest that is incomplete. 37 CFR 1.291(c) does not provide for the submission of additional protests in the same application by the same real party in interest except for submissions filed in accordance with 37 CFR 1.291(c)(5). Multiple piecemeal protests (raising a slightly different issue in each protest submission) in a single application by the same real party in interest are not permitted. After the filing of the protest, no further submission of prior art by the same real party in interest will be considered, except for new, non-cumulative prior art submitted under the conditions of 37 CFR 1.291(c)(5). 37 CFR 1.291(c)(5) requires that a second or subsequent protest by the same real party in interest include:
  • (A) an explanation as to why the issue(s) raised in the second or subsequent protest are significantly different than those raised earlier;
  • (B) an explanation as to why the significantly different issue(s) were not earlier presented; and
  • (C) the processing fee under 37 CFR 1.17(i).

New Non-Cumulative Prior Art May Raise New Issues
Note:
Submission of new, non-cumulative prior art may introduce significantly different issues in a protest, but additional comments with the same data do not qualify as such.

Significantly different issue(s) may be raised by the submission of new, non-cumulative prior art or other information not previously made of record. Additional comments seeking to bring in further or even new data or information with respect to an issue previously raised by the same real party in interest would not qualify as a significantly different issue. By imposing requirements for second or subsequent protests on "the same real party in interest," the requirements of 37 CFR 1.291(c)(5) cannot be avoided by multiple protests submitted by different people representing the same real party in interest.

Same Party Cannot Avoid Protest Rules
Note:
The rule prevents the same real party in interest from avoiding protest requirements by submitting multiple protests through different representatives.

Significantly different issue(s) may be raised by the submission of new, non-cumulative prior art or other information not previously made of record. Additional comments seeking to bring in further or even new data or information with respect to an issue previously raised by the same real party in interest would not qualify as a significantly different issue.

Requirement for Timely Second Protest
Note:
