There is, of course, no excuse for submitting a poorly-worded patent application.
However, while knowing that more than 20 claims costs extra but is allowable, coupled with the fact that upon PTO Action we can only remove from, not add to claims, plus the Examiner is directed to be "helpful" to per se applicants, so as a wild strategy:
Can we add multiple similar claims with slight wording "tweaks" as a per se applicant in the hopes the Examiner will strike the "least applicable" ones while also aiding the Examiner? What would actually happen to such an application?
For example (putting aside patentability and connecting parts):
Claim 1. A toy boat comprising a hull and a fan. Claim 2. The toy boat of Claim 1, wherein said fan propels said hull. Claim 3. The toy boat of Claim 1, wherein said fan urges said hull. Claim 4. The toy boat of Claim 1, wherein said fan imparts thrust on said hull. ... drives ... ... acts as an engine for ... ... behaves as an engine for ... ... characterizes an engine for ... More about that "being helpful" comment:
Manual of Patent Examining Procedure, Section 707.07(j), states: When, during the examination of a pro se [no attorney] application it becomes apparent to the examiner that there is patentable subject matter disclosed in the application, the examiner should draft one or more claims for the applicant and indicate in his or her action that such claims would be allowed if incorporated in the application by amendment.
