The opinion of the court was delivered by: Hon. Dana M. Sabraw United States District Judge
ORDER: (1) GRANTING IN PART PLAINTIFF'S MOTION TO STRIKE THE DECLARATION OF CLARK AND SOMMERFELD (2) DENYING DEFENDANT'S MOTION FOR SUMMARY JUDGMENT OF INVALIDITY OF KREG TOOL [Docs. 222 & 240] AND ALL RELATED COUNTERCLAIMS.
Pending before the Court is Defendant's motion for summary judgment of invalidity of Claim 5 of U.S. Patent No. 7,374,373 ('373 Patent) under 35 U.S.C. § 102(a) and (b) as anticipated by Defendant's product, the Foreman DB50 Pocket Hole Drilling Machine. Also pending is Plaintiff's motion to strike several declarations filed by Scott Clark and Todd Sommerfeld. The matters came on for hearing on May 7, 2010. Paul Adams appeared on behalf of Plaintiff. Timothy Zarley and Maha Sarah appeared on behalf of Defendant. For the reasons set forth below, Defendant's motion is denied and Plaintiff's motion is granted in part.
Three patents are at issue: United States Patent Nos. 6,637,988 ('988 Patent), 7,134,814 ('814 Patent) and 7,374,373 ('373 Patent). All three patents are part of a family of patents, covering woodworking tools for drilling pocket holes. Because the facts are well known to the parties, the Court discusses only those facts that are relevant to the disposition of the subject motion.
Plaintiff brought suit alleging that Defendant's DB55 and DB110 pocket hole drilling products infringed Claim 14 of the '373 patent. Claim 14 is dependent on Claim 13, which in turn is dependent on Claim 5. Defendant filed a counterclaim asserting that the '373 patent is invalid. Defendant now moves for summary judgment of invalidity of Claim 5 of the '373 patent. Claim 5 provides:
An apparatus for drilling pocket-holes into a workpiece for use cooperatively with a step drill, comprising: a body, said body having a work surface defining a plane; a drilling module for cutting the pocket-hole, said drilling module having a first motor for driving a step-drill, wherein said drilling module is movable in a drilling direction from a first position to a second position by an actuator, wherein the step-drill intersects said plane; a guide module, said drilling module slidably mounted thereon, said drilling module engaging with respect to said guide module in said drilling direction; and an adjustable fence mounted on said work surface to position the workpiece so that the depth of drilling can be adjustable.
This Court previously held that the accused DB55 and DB110 products do not infringe the '373 patent. (Doc. 180.) The Court's order was based on the lever-sequence described in Claim 13 of the patent. Claim 13 provides:
The apparatus as claimed in claim 5, further comprising a clamp which is movable to secure the workpiece, wherein said actuator provides a first point, a second point and a third point, wherein the movement of said actuator from said first point to second point causes clamping the workpiece by said clamp and the movement of said actuator from said second point to third point causes said drilling module to move to cut the pocket-hole in the workpiece by said first motor.
In Claim 13, "movement of the actuator from the first to the second point causes the clamp to engage the workpiece without movement of the drilling module, while movement of the actuator from the second to the third point causes movement of the drilling module." (Doc. 63 at 24-25.) In the accused products, the clamp and drilling module move simultaneously, and thus, do not infringe the patent either literally or under the doctrine of equivalents. (Doc. 180 at 4-7.)
After Defendant filed its motion for summary judgment of non-infringement of the '373 patent, Plaintiff filed a cross-motion for summary judgment of validity and infringement. (Doc. 110.) The Court denied Plaintiff's motion as moot after ruling that Defendant's products do not infringe the '373 patent. (Doc. 180.) Plaintiff, therefore, did not oppose the instant motion on the merits, but instead argued the issue was moot because of the Court's previous ruling. However, because of the public interest in adjudicating issues of validity, Cardinal Chem. Co. v. Morton Int'l, 508 U.S. 83, 100 (1993), the Court finds that addressing the merits of Defendant's claims is warranted. While Plaintiff was permitted to, and did, file a supplemental brief, he did not oppose the motion on the merits; instead, Plaintiff argues the issue is moot because he intends to file for a reissue patent in the United States Patent and Trademark Office ("USPTO"). (Doc. 266.)
Plaintiff moves to strike declarations filed by Scott Clark and Todd Sommerfeld on the grounds that Clark and Sommerfeld, who were not designated as experts, are providing expert testimony. Sommerfeld's declarations were filed with motions later withdrawn by Defendant and the Court has already ruled on the motion involving the Clark declaration. Nevertheless, a ruling on the motion is warranted to guide the parties at trial.
Clark is a designer at Kreg Tool and co-inventor of the K3 device. Sommerfeld is the President of Kreg Tool and a named inventor of U.S. Patent No. 6,481,937. Defendant contends Clark and Sommerfeld are inventor lay witnesses who are testifying as to personal knowledge of their own products. Defendant further contends, citing Sitrick v. Dreamworks, LLC, 2006 U.S. Dist. LEXIS 97312, 64-66 (C.D. Cal. July 20, 2006), that Clark and Sommerfeld are free to compare their products with Park's patents. In Sitrick, the court allowed an inventor to testify about his own product and to compare it to the accused product. Id. There, however, the inventor was also the founder and managing director of the company that developed the accused product, and the court found that the inventor's statement was one of fact based on personal knowledge. Id. The court did not permit the inventor to render opinions. Id. at 65 n.9. Likewise, Clark and Sommerfeld may testify as to the features of their own inventions, as well as to any other of Defendant's products for which they have personal knowledge. Clark and Sommerfeld, however, may not compare and ...
