Appeal No. 1999-2186
Application No. 08/857,571
Geoffrey Henry Schuler (filed Aug. 26, 1998). According to
the qualifications stated in the delcaration, Mr. Schuler, an
industrial chemist of long experience, appears to be well
versed on the subject of rubber. He states that pencil
erasers and ink erasers must each have certain
characteristics, and identifies the materials from which each
may be made. Attached to the declaration as Annexures ‘A’ to
‘F’ are six items made of various rubber compositions, natural
and/or synthetic. Annexure ‘A’ is a pencil eraser, Annexure
‘B’ is an ink/pencil eraser, and Annexures ‘C’, ‘D’, ‘E’ and
‘F’ are four other items, which
Mr. Schuler states are unsuitable or ineffective to remove
writing from paper. He concludes in paragraph 22 that "only
the substances in Annexures A and B are suitable for use as an
eraser, to remove writing from normal paper."
Concerning the Schuler declaration, the examiner states
on pages 8 and 9 of the answer:
the disclosure of Lundy does not preclude the
use of any of the rubber samples from being used
in his tee construction. Therefore, it is seen
as being obvious within the teachings of Lundy
to one of ordinary skill in the art to form the
shaft of the tee from any rubber, including
those that are effective in erasing writing.
