Post by TobyI have a working prototype, for which I want to file a provisional patent.
Are photos acceptable--with appropriate captioning, or do they have to be
drawings? Photos sure would be easier...
I have filed a number of utility patent applications using annotated
digital photographs instead of line drawings, and there the drawings
will be examined by the examiner and the draftsman for compliance with
the drawing rules. Since there are no format requirements for a
provisional application and it will never be examined, there's even less
reason not to use photographs in a provision - we do it all the time to
save the expense of drafting. You do want to be sure that the photos are
clear, contrasty and black-and-white.
The first few times I filed photos, it was because there wasn't time,
with the intention of later replacing the photos with drawings - I was
amazed when the patents issued with the photographs "as is". Since then,
I've used photos frequently where the client was budget sensitive or the
drawings wouldn't have been as clear, and in many, if not most, cases
they were accepted.
