I filed my first patent application several years ago. Now I have received a letter asking me to elect a species. I have no experience with this sort of thing, but it appears that the patent examiner has made an error. I've drafted a response, and I would love to hear suggestions.
Examiner, Art Unit 3632
U.S. Patent Office
Dear Ms. Smith:
This is concerning your letter dated January 31, 2011 regarding patent application 11/601,964. As I understand your letter, your office claims that the application contains multiple inventions that “are independent or distinct because they reveal various embodiments of the mount.” For this reason, I must elect a specific species of the invention, with the claims associated with that species, for examination to go forward.
I understand that, whether or not I choose to appeal the decision to hold these as distinct species (what I believe is called a “traverse”), I am required to elect a species for this patent application to go forward, including which claims go with the elected species. For this reason, in response to the Requirement for Restriction, I elect with traverse, the species identified by Figs. 1-5, corresponding to claims 1-4, for examination.
My traverse argument is that your letter of January 31, 2011 is incorrect in that it states that I must elect a specific species because multiple inventions “are independent or distinct.” [emphasis added] As specified in MPEP § 802, 35 USC 121, and 37 CFR 1.142 the requirement for restriction applies “If two or more independent and distinct inventions are claimed in a single application…” [emphasis added]
By the definition of “related but distinct” in MPEP § 802.01(II), the three species contained in Figs. 1-5, 6-11, and 12-14 are not “independent and distinct.” They are actually “related but distinct.” I make this argument based on the definition of “related but distinct”: “Two or more inventions are related (i.e., not independent) if they are disclosed as connected in at least one of design (e.g., structure or method of manufacture), operation (e.g., function or method of use), or effect.” The three embodiments in Figs. 1-5, 6-11, and 12-14 are therefore related because they are “connected” in “design,” in “operation,” and in “effect.”
In Design
Figs. 1-5, 6-11, and 12-14 all use a retaining pin that goes axially or chordally perpendicular to the direction of movement of the counterweight on the counterweight shaft. The only difference in these three species is whether the retaining pin goes into the counterweight shaft itself, or into one of two different extensions to the counterweight shaft, depending on whether the counterweight shaft holds the existing counterweight retention device with a threaded hole or a threaded stud.
In Operation
Once the counterweight shaft extension is installed, the invention operates identically in all three embodiments: the user removes the retaining pin to allow removal or installation of the counterweight. It thus meets the “operation” requirement.
In Effect
All three embodiments work in exactly the same way—using the strength of the retaining pin to prevent a counterweight from sliding off the end of the counterweight shaft. All three embodiments have the same effect.
If necessary, claim 1 could be corrected to:
1. A counterweight retention safety device for a German equatorial telescope mount, comprising a retaining pin passing through a diametric or chordal through-hole in the counterweight shaft or attached extension of the counterweight shaft of said mount, with said retaining pin having sufficient length to extend beyond the diameter of the counterweight shaft, where said retaining pin functions as a stop to arrest the axial movement of counterweights along said counterweight shaft.
Please let me know what steps I need to take next.
Very Truly Yours,
Clayton E. Cramer
