Opinions

ALMOND, Judge.

Melott appeals from the decision of the Board of Appeals affirming the examiner’s rejection of claims 2 to 11, inclusive, in appellant’s application1 for “Aspirating Syringe.” The board reversed the examiner’s rejection of claims 12, 13 and 14.

Claim 2 is reproduced as illustrative:

“An aspirating syringe for use with a cartridge having a piston cork, said syringe comprising a barrel for reception of the ampoule or [888]*888cartridge, a needle at one end of the barrel, means for puncturing the cartridge for leading the contents thereof to the needle, a retractible syringe plunger rod, a head at the other end of the barrel and slidably containing the plunger rod, the rod extending into the barrel, and piercing means on the plunger rod at its inner end for connection thereof with the cartridge plunger cork, said piercing means being relatively sharp and capablé of piercing the cartridge plunger cork by a straight in-line push on the plunger rod.”

The drawing portrays the following:

The claimed invention relates to a cartridge-type syringe having a plunger rod 32 with a retractible spearpoint head 38 at the inner end thereof for piercing the piston cork 22 of the cartridge or ampoule affixing the plunger rod to the cork, thus converting the syringe into an aspirating as well as an inspirating [889]*889means. In use of the device the locking sleeve 24 is backed off; the head 26, attached by hinge means, is pivoted to one side and the cartridge is inserted in the barrel. The head is then repositioned, the rod 20 is moved forwardly so as to engage the flange 36 with the exterior surface of the cartridge cork. Forward pressure on the plunger rod 20 results in piercing cork 22 by spear-point 38 until it becomes completely ■embedded therein as shown in Fig. 2. Disposal of the cartridge is accomplished by retraction of rod 32 by pull-on finger piece 58 thus bringing the spearhead hack in housed position in the sleeve as .shown in Fig. 6. This action dislodges the spearpoint from the cork 22, allowing the entire cartridge to be disposed of, and readies the barrel for insertion of new ■cartridges. It is asserted that the spear-point is more easily withdrawn from the cork due to the sharp edges 44 on the barbs 42. The spearpoint may be made integral with rod 32 or separable and replaceable by means of screw-threads such as shown at 40 in Fig. 2. The outer end of rod 32 is provided with an enlargement 54 serving as a guide and abutment for a coil spring 56 which functions to maintain the spearpoint in retracted housed position when not in use.

The references relied on by the board are:

Effenberger 773,857 Nov. 1, 1904

Pontius 2,693,804 Nov. 9, 1954

Breitenbach 2,789,559 Apr. 23, 1957

Hein 2,833,280 May 6, 1958

Effenberger shows a pointed spear-like barb for straight-line piercing engagement with a bottle cork for removal of the cork from the bottle.

Pontius shows a syringe plunger rod comprising an inner rod slidable in an ■outer sleeve and having three pointed barblike prongs for locking engagement with a syringe piston cork. The outer :sleeve is designed to abut the cork to facilitate removal of same from the prongs.

Breitenbach shows an aspirating and injecting syringe with a plunger rod comprising an inner rod slidable in an outer sleeve having prongs horn-shaped with the points curved inwardly for engaging a syringe piston cork. The prongs engage the cork by simultaneous forward pressure and twisting motion of the inner rod.

Hein shows a spring between an inner rod and outer sleeve of a plunger rod. The spring functions to hold the inner rod and outer sleeve in engagement with a syringe piston.

Claims 2-14 were rejected by the examiner as unpatentable over either Pontius or Breitenbach “in view of the well known use of barb prong connecting means for engaging stoppers as typified by Effenberger,” stating that the claims differed from the references “only in the particular type of plunger-piston connector employed on the end of the inner plunger rod.” With respect to claims 10-11 the examiner regarded' as conventional the resilient means of Hein normally retracting the inner rod and piston cork connector within the outer sleeve.

The board held that claims 2 to 9 do not patentably distinguish over Pontius. It interpreted Effenberger as cumulative, pointing to it, however, as an example of a barbed rod. It held that claim 5 was anticipated by Breitenbach since the claws of that reference are integral with the plunger rod and the claim does not preclude the rotary motion of the rod of the reference; that claim 7, absent its use provisions, recited a mere plunger rod not distinguishable from that shown in Effenberger and that recitation in claims 10 and 11 of resilient means to retract the piercing means within the plunger rod avoids Breitenbach in this respect only but Hein discloses and clearly teaches the addition of such means to Breitenbach for the same purpose in. the same kind of device.

Appellant relies strongly on the board’s evaluation of the Effenberger reference in its reversal of the examiner as to claims 12, 13 and 14. In this connection the board said:

“Effenberger relates to a bottle cork having a permanently embed[890]*890ded, barbed rod with a handle for extraction of the cork from a bottle. The patentee explains in line 24 of page 1 that the “extractor ‘when applied cannot be pulled from its connected and operative relation with the body of the cork.’ He thus teaches a connection and operation directly opposed to that of appellant, Pontius or Breitenbach. In combining references patentability cannot be negatived merely by selecting from the prior art those features which can be synthesized into an anticipation once it is known what features should be selected. The Effenberger device thus fails to supply the necessary feature which Pontius or Breitenbach alone does not possess, that is, the teaching of the deficiency and how to solve it.”

From this premise, counsel for appellant argues that the board has thus rendered the Effenberger patent of no effect as a combining reference and restricted the references depended upon to: Pon-tius alone as to claims 2 to 9; Breiten-bach alone as to claim 5; Effenberger alone as to claim 7; and Breitenbach in view of Hein as to claims 10 and 11.

As we have above noted, the board in sustaining the examiner’s rejection of claims 2 to 9 on Pontius interpreted the Effenberger reference as cumulative “as an example of a barbed rod.” We take it, therefore, that the Effenberger reference is before us for whatever it may be worth in relation to the issue of obviousness. In In re Wright, 256 F.2d 583, 45 CCPA 1005, appellant asserted a position similar to that advanced here. This court stated that the board’s reasons for allowing other claims before it are irrelevant and that the court’s only concern was “whether the appealed rejected claims have been properly acted upon by the board * *

Appellant contends that the entire theory and operation of Pontius differ completely from his disclosure in that the reference shows claws in a grasping action on the cartridge cork as distinguished from appellant’s spearpoint, sharp on its forward edges, with a piercing function that will not tear the cork as in claw-like means.
