Fragale in view of O’Hanlon. It is the examiner’s finding
that Fragale discloses the claimed insulative insert for use
in a corner member of siding which is L-shaped and fits snugly
into the flanges of the associated corner member. The
examiner states that Fragale does not disclose a one-piece
insert which is resilient and compressible. The examiner
finds that O’Hanlon discloses a similar corner construction
comprised of a one-piece
insert and associated corner members and that the O’Hanlon
insert may be any suitable type of polyurethane which may be
rigid or flexible. The examiner concludes:
The use of a one-piece insert (as taught by
O’Hanlon) for Fragale would have been
obvious to one of ordinary skill in the
art, so that fewer components would be
needed at the construction site, and
assembly of the corner/insert would be made
easier-- i.e. workers would only have to
install one member into the corner as
opposed to two or more section[s] of the
foam material, which would make
installation easier since one component
would be received and held in the corner
without the need for manually holding
several foam insert sections within the
corner. The use of compressible/flexible
foam materials (as taught by O’Hanlon) for
Fragale’s foam insert would have been
obvious to one or ordinary skill in the
art, since this material was well known in
