Appeal No. 1998-0328
Application No. 08/383,251
The subject matter here claimed is a “[m]etallic ball pin
of a universal joint for motor vehicles” (claim 1, line 1).
The ball pin comprises a machined joint ball (2) and a pin
stump (1). The pin stump is formed with a fastening pin (4)
received in a hole or bore (5) formed through the ball. The
ball is non-rotatably mounted on the fastening pin and is also
confined against axial movement on the fastening pin. All of
the independent claims on appeal, namely claims 1 and 14,
recite that the fastening pin is “formed by cold forming in a
direction of a longitudinal axis of said pin stump.”
A copy of the appealed claims is appended to
appellants’ brief.
The following references are relied upon by the
examiner as evidence of obviousness in support of his
rejections under 35 U.S.C. § 103:
