BACKGROUND
The appellants' invention relates to a method of
acquiring position information by detecting predetermined
patterns of magnetic substance in a substrate formed with
grooves filled with the magnetic substance. An understanding
of the invention can be derived from a reading of the sole
appealed claim 2, which is reproduced below.
2. A method comprising providing a substrate formed with
grooves arranged in accordance with predetermined patterns and
a magnetized magnetic substance filling said grooves, using
said substrate with said magnetized substance as a magnetic
scale including detecting said predetermined patterns to
acquire information on a position.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Henrich et al. (Henrich) 3,768,094 Oct.
23, 1973
Marechal et al. (Marechal) 4,899,037 Feb. 06,
1990
Claim 2 stands rejected under 35 U.S.C. § 112, second
paragraph, as failing to particularly point out and distinctly
claim the subject matter which applicants regard as the
invention. Claim 2 stands rejected under 35 U.S.C. § 103 as
being unpatentable over Henrich in view of Marechal.
