TONY N. LEUNG, Magistrate Judge.
This matter is before the Court on Defendants' Motion to Reduce Asserted Claims. (Case No. 14-cv-4666, ECF No. 155; Case No. 14-cv-4669, ECF No. 167; Case No. 14-cv-4671, ECF No. 158; Case No. 14-cv-4672, ECF No. 164). These motions were referred to the undersigned for a report and recommendation to the Honorable John R. Tunheim, Chief United States District Judge for the District of Minnesota, pursuant to 28 U.S.C. § 636. The Court held a hearing on October 26, 2016 and heard argument from all parties. (ECF No. 185).
Plaintiff Regents of the University of Minnesota ("the University") filed suit accusing Defendants of infringing five patents across two patent families. Put simply, the University alleges that Defendants infringe upon its patents via their 4G LTE networks. Patent Nos. 7,251,768 ("'768 patent") and RE45,230 ("'230 patent") relate to error coding and linear precoding, techniques that are used to ensure data transmission reliability. The other patent family, Nos. 88,718,185 ("'185 patent"), 8,774,309 ("'309 patent"), and 8,588,317 ("'317 patent"), relates to channel and carrier frequency offset estimation, which permits mobile phones to measure and compensate for certain types of inaccuracies in data transmission.
The five patents contain 184 total claims, and the University is currently asserting 129 separate infringement claims. Regarding the `768 and `230 patents, the University initially asserted 10 of the 28 claims in the `768 patent (4 independent claims and 6 dependent claims) and 58 of the 77 claims in the `230 patent (9 independent claims and 49 dependent claims). For the other patent family, the University initially asserted 8 of the 20 claims in the `317 patent (2 independent claims and 6 dependent claims), 27 of 30 claims in the `185 patent (3 independent claims and 24 dependent claims), and 25 of the 29 claims in the `309 patent (9 independent claims and 16 dependent claims). The University contends that each of the claims represents a distinct invention and that many of the claims provide unique issues of infringement and validity.
After discussion among the parties, the University has agreed to reduce its 129 claims down to 45 claims before claim construction. (See, e.g., ECF No. 173, at 3). The University further agrees to reduce down to 20 claims shortly after the close of fact discovery. (See, e.g., ECF No. 173, at 3). Defendants contend that case law demands the University immediately reduce its claims even further to 15.
"The Federal Circuit has held that district courts possess the authority and discretion to reasonably limit the number of claims asserted in patent infringement actions, subject to due process considerations." Select Comfort Corp. v. Gentherm, Inc., 2014 WL 4976586, at *1 (D. Minn. Oct. 3, 2014) (citing In re Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1313 (Fed. Cir. 2011)). A party asserting patent infringement must be permitted sufficient discovery to allow it "to determine whether its asserted claims raise separate issues of infringement in light of [a defendant's] accused products and defenses," necessarily requiring discovery into a defendant's infringement and invalidity contentions prior to claim reduction. Arctic Cat, Inc. v. Polaris Indus. Inc., 2015 WL 3756409, at *4 (D. Minn. June 12, 2015) (citation omitted). However, "waiting to reduce claims until after claim construction would be too late in the litigation process. Indeed, the vast majority of courts that have ordered claim reduction have done so prior to claim construction." Id. (citations omitted). If a district court reduces claims, it must leave "open the door for the assertion of additional claims on a showing of need." Stamps.com Inc. v. Endicia, Inc., 437 Fed. Appx. 897, 902 (Fed. Cir. 2011) (discussing In re Katz, 639 F.3d at 1309-12).
Here, Defendants assert primarily that Select Comfort stands for the proposition that the University must limit itself to 15 infringement claims before claim construction, and even fewer claims come trial. The Court disagrees. In Select Comfort, Plaintiff Select Comfort Corp. brought suit seeking declarations of non-infringement and invalidity as to certain patents held by Defendant Gentherm, Inc., with Gentherm counterclaiming for patent infringement as to five of its patents.
Here, the University's suit is for patent infringement claims relating to 4G LTE transmissions, an extremely complicated technology that is ubiquitous in modern life. Without better understanding which of the University's claims are viable and which are not—an understanding that will only be gained through further fact discovery that is far from being concluded—the Court has a paucity of information against which to gauge what an appropriate number of claims should be in this case. Cf. In re Katz, 639 F.3d at 1313 n.9 ("[A] claim selection order could come too early in the discovery process, denying the plaintiff the opportunity to determine whether particular claims might raise separate issues of infringement or invalidity in light of the defendants' accused products and proposed defenses."). To grant the relief requested by Defendants, the Court would not be partaking in a well-reasoned procedure under a workable standard, but would instead be engaging in metaphysical conjecture to choose a number that sounds reasonable as compared to numbers in other cases—cases that do not involve subject matter as technically complicated or pervasive as that here.
