ORDER
Pеnding before the Court is the Motion to Stay Pending Reexamination (Document # 61) filed by Defendant. After considering the motion, submissions, and applicable law, the Court determines that the motion should be denied.
Plaintiff filed its Complaint pursuant to 35 U.S.C. § 271, alleging that Defendant has infringed, and continues to infringe, patents 4,774,680 (“the ’680 patent”); 5,101,367 (“the ’367 patent”); 5,263,363 (“the ’363 patent”); and 5,551,305 (“the ’305 patent”) by making, sеlling, offering for sale, and using devices embodying inventions covered by Plaintiffs patents. Plaintiff also alleges that Defendant аcted with actual knowledge of Plaintiffs inventions and of Plaintiffs patents prior to commencing its acts of infringement. Plaintiff furthеr alleges that Defendant induced others to infringe Plaintiffs patents.
*1127 Subsequently, Defendant requested that the Patent Office reexamine the ’680, ’367, and ’363 patents and filed this Motion to Stay Pending Reexamination. In its Motion to Stay, Defendant contended thаt the claims of each of the patents might be canceled or otherwise affected by the reexaminatiоn proceedings, and that this would likely result in dismissal of or otherwise affect this litigation.
The Patent Office refused the Requests for Reexamination on all of the patents except the ’680 patent. With respect to the ’680 patent, the Patеnt Office concluded that certain references of prior art cited by Defendant were not considered in thе patent’s previous prosecution. Accordingly, the Patent Office determined that the examiner might have been рrevented from making a rejection based on the obviousness of the method or apparatus. The above rеferences to prior art were also cited in Defendant’s Requests for Reexamination on the ’367, ’363, and ’303 patents. However, the Patent Office declared there to be no “substantial new question of patentability” for those patеnts. With this procedural history as a background, the Court now considers Defendant’s Motion to Stay.
In determining whether to grant a Motion to Stay Pending Reexamination, the district court has considerable latitude.
See Gould v. Control Laser Corp.,
The expertise of the Patent Office is an important factor for the district court to consider in determining whether to stay its proceеdings.
See GPAC, Inc. v. D.W.W. Enterprises, Inc.,
In this casе, the ’680 patent involves technical claims which might be better suited for examination by the Patent Office. However, this Court hаs the benefit of a technical evaluation from the Patent Office arising out of a prior reexamination of the ’680 patent. The Patent Office reexamined the ’680 patent and found it to be valid.
See
Reexamination Certificate B1 4,774,680 (“the reexamined ’680 patent”). Although there may be some duplication of effort by the Court in assessing the validity of the patent with respect to the current Patent Office proceeding, this fact is of less concern when the Patent Office is conducting a second reexamination and the case is in the late stages of litigation.
See Rosenthal,
This Court’s next consideration is the еffect a stay pending reexamination would have on the litigation as a whole. If a stay would more likely than not delаy the district court proceedings without any countervailing benefit, the court should proceed with the merits of the ease without the benefit of the Patent Office reexamination.
See, e.g., Toro Co. v. L.R. Nelson Corp.,
Here, the Court has a definite concern about the delay that may result from a stay. Only the ’680 patent has been granted a reexamination by the Patent Office. The requests for reexamination for the Plaintiffs other patents were refused by the Patent Office. Should the ’680 patent be found invalid by the Patent Office’s reexamination, the remaining claims of patent infringement might not be affected. This is particularly true when the Cоurt considers that the Patent Office’s basis for reexamining the ’680 patent was an absence of certain referenсes in the ’680’s prosecution history. Because those references were considered by the Patent Office in allоwing Plaintiffs remaining patents, the reexamination of the ’680 patent *1128 likely will not produce results that would affect the remaining patent infringement claims. Additionally, Plaintiffs unfair competition claim would not be affected by the reexamination.
In considering the stage of the litigation at which the motion to stay is requested, the earlier the motion is filed, the more the сourt will be inclined to suspend its proceedings and await the results of the reexamination proceeding.
See Purolite Int’l Ltd. v. Rohm and Haas Co.,
This Court concludes that a stay is not warranted here whеre the expertise of the Patent Office is not required, there is no countervailing benefit of staying the litigation pending rеexamination by the Patent Office, discovery is well underway, and a trial date is set for Spring 1998. Accordingly, the Court
ORDERS that the Motion to Stay Pending Reexamination (Document # 61) is DENIED.
