4WEB, INC. and 4WEB, LLC, Plaintiffs, v. NUVASIVE, INC., Defendant.
Case No.: 24-cv-01021-JLS-MMP
UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF CALIFORNIA
May 28, 2025
HON. MICHELLE M. PETTIT
ECF No. 171
[ECF No. 149]
In this patent infringement action, 4WEB asserts NuVasive‘s “Modulus” spinal implant products1 (“Accused Products“) infringe nine of 4WEB‘s United States Patents2 related to 3D-printed, titanium interbody fusion devices. ECF No. 21 ¶ 62. Before the Court is 4WEB‘s Motion to Compel NuVasive to Answer Interrogatory No. 6 pursuant to
I. RELEVANT DISCOVERY BACKGROUND
4WEB‘s Interrogatory No. 6 provides:
For each of the Accused Products, identify, by month from release of the first sale to the present date, an explanation of what was sold if the sale involved bundling any of the Accused Products with any other product for the number of units sold (either alone or in combination with other accessories or products).
ECF. No. 149-3 at 10.
NuVasive initially asserted objections based on relevance, undue burden, and proportionality. ECF No. 149-3 at 10. NuVasive also found the interrogatory unintelligible, vague, and ambiguous. Id. In its First Supplemental Response, NuVasive further objected
4WEB contends NuVasive‘s response is deficient because it fails to identify (other than the Modulus ALIF Blades and Modulus XLIF Plates) the accessory products sold alongside the Accused Products. ECF No. 149-1 at 3.
On February 26, 2025, the Court held an informal discovery conference regarding this dispute. ECF No. 135. After hearing from both sides, the Court directed the parties to further meet and confer as to the scope of information sought in Interrogatory No. 6 and NuVasive‘s claimed burden. If the parties did not agree after the meet and confer the Court, Plaintiff was permitted to file a motion to compel.
Following the Court‘s discovery conference, 4WEB modified its request to seek financial information on a yearly rather than monthly basis for accessories that are functionally related to the Accused Products, which it believes are: (i) supplemental fixation products; (ii) integrated fixation products; (iii) biologics; (iv) neuromonitoring equipment; (v) neuromonitoring services; (vi) neuromonitoring instruments and
II. LEGAL STANDARD
Parties may obtain discovery regarding any nonprivileged matter that is relevant to any party‘s claim or defense and proportional to the needs of the case, considering the importance of the issues at stake in the action, the amount in controversy, the parties’ relative access to relevant information, the parties’ resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit.
“An interrogatory may relate to any matter that may be inquired into under
Any party, on notice to all other parties and all affected persons, may apply for an order compelling discovery.
The party seeking to compel discovery has the burden of establishing relevance. Alves v. Riverside Cnty., 339 F.R.D. 556, 559 (C.D. Cal. 2021). “District courts have broad discretion in determining relevancy for discovery purposes.” Surfvivor Media, Inc. v. Survivor Prods., 406 F.3d 625, 635 (9th Cir. 2005) (citing Hallett v. Morgan, 296 F.3d 732, 751 (9th Cir. 2002)). “Once the propounding party establishes that the request seeks relevant information, ‘[t]he party who resists discovery has the burden to show discovery should not be allowed, and has the burden of clarifying, explaining, and supporting its objections.‘” Goro v. Flowers Foods, Inc., 334 F.R.D. 275, 283 (S.D. Cal. 2018) (internal citations omitted). “The party resisting discovery must specifically detail the reasons why each request is objectionable, and may not rely on boilerplate, generalized, conclusory, or speculative arguments.” Licea v. Beshay Foods, Inc., No. 19-cv-1565-JM-AHG, 2020 WL 1975059, at *1 (S.D. Cal. Apr. 23, 2020) (citing F.T.C. v. AMG Servs., Inc., 291 F.R.D. 544, 553 (D. Nev. 2013)). “Arguments against discovery must be supported by specific examples and articulated reasoning.” Id. (citation and quotations omitted).
In ruling on a motion to compel discovery, the court has discretion to modify the discovery requests rather than sustain the responding party‘s objections in total. See Green v. Baca, 219 F.R.D. 485, 490 (C.D. Cal. 2003); see Licea, 2020 WL 1975059, at *2 (recognizing a district court may “expand, limit, or differ from the relief requested“).
III. ANALYSIS
A. The Parties’ Positions
4WEB contends this interrogatory seeks “basic financial information related to accessory products sold alongside—i.e., ‘bundled’ with—the Accused Products” relevant to its damages theories. ECF No. 149-1 at 1, 7. 4WEB further contends the information sought is relevant because the jury will consider the Georgia-Pacific factors, including the extent of convoyed sales, in its reasonable royalty calculation related to damages. Id. at 2. 4WEB argues the discovery of all Accessory Products is proper because “they are functionally related to the Accused Products,” and thus sales of the Accessory Products along with the Accused Products would be reasonably foreseeable. Id. at 6-7; see ECF No. 151 at 5. In addition, 4WEB contends the information sought is proportional to the needs of the case—particularly in light of the amount in controversy and the parties’ resources—and the information is “squarely within” NuVasive‘s possession. ECF No. 149-1 at 2.
NuVasive objects, asserting 4WEB has failed to carry its burden to show any—let
B. Analysis
4WEB contends Interrogatory No. 6 is relevant to its reasonable royalty calculation. A court will “award the claimant damages adequate to compensate for [patent] infringement, but in no event less than a reasonable royalty.”
In its March 17, 2025 Order, the Court addressed a request for production (“RFP“) seeking documents related to 4WEB‘s convoyed sales theory. ECF No. 145 at 16-19. This Court found 4WEB‘s RFP did not identify specific products relevant to its convoyed sales theory and was not narrowly tailored. Id. at 18-19. The Court expressly noted 4WEB is likely entitled to information about NuVasive‘s non-accused products with a more targeted search, but the RFP was overly broad as written. Id. at 19.
4WEB contends this interrogatory, as narrowed, “identifies specific categories of Accessory Products that are sold alongside (i.e., ‘bundled‘) with the Accused Products” and “aligns with how NuVasive identified functionally related [non-accused] products in its prior litigation involving spinal implants.” ECF No. 149-1 at 4 (emphasis omitted). 4WEB relies on a report in another matter, NuVasive, Inc. v. Alphatec Holdings, Inc., No. 18-cv-347-CAB-MDD, in which NuVasive‘s expert opined that access tools, implants, and neuromonitoring necessary to perform the XLIF (eXtreme Lateral Interbody Fusion) procedure were all “functionally related” to a different patented spinal implant system at issue in that case. See ECF No. 149-3 at 41-60, ¶ 26. 4WEB contends it specifically identifies “access tools” such as retractors, blades, shims, and neuromonitoring equipment, as well as several accessories it contends are “specifically designed to improve surgical outcomes, such as biologics and fixation tools.” ECF No. 149-1 at 6-7 (citing ECF No. 149-3 ¶ 26, quotations and emphasis omitted). 4WEB contends these are all functionally related to the Accused Products, and therefore relevant and discoverable. Id. at 7.
In opposition, NuVasive contends 4WEB “ignores that each of the Accessory Products ‘has a use independent of the patented device, that suggests a non-functional relationship.‘” ECF No. 150 at 3 (quoting Warsaw Orthopedic, Inc. v. NuVasive, Inc., 778 F.3d 1365, 1375 (Fed. Cir. 2015)). NuVasive contends the Accessory Products can be used
In reply, 4WEB counters NuVasive‘s arguments go to admissibility at trial when calculating a reasonable royalty but should not prevent NuVasive from providing the requested information during discovery. ECF No. 151 at 3 (citing Haworth, Inc. v. Herman Miller, Inc., 162 F.R.D. 286, 288 (W.D. Mich. 1995)). 4WEB also contends it seeks information related to convoyed sales in the context of reasonable royalties (as opposed to lost profits), which requires a lower showing that the Accessory Products may be promoted by the sales of the Accused Products (as opposed to no independent use). See Tr. 13-14.
The Court finds 4WEB has made a sufficient showing of relevance for purposes of discovery. “In patent cases where the plaintiff does not claim lost profits, damages are assessed by determining the ‘reasonable royalty’ the plaintiff would have received through arms-length bargaining. [] The court tries to calculate the royalty upon which the parties would have agreed had they successfully negotiated an agreement just before the infringement began.” Positive Techs., Inc. v. Sony Elecs., Inc., No. 11-cv-2226-SI-KAW, 2013 WL 707914, at *3 (N.D. Cal. Feb. 26, 2013) (citation omitted). Here, the effect of selling the Accused Products in promoting sales of surgery tools and accessories (e.g., fixation, biologics, neuromonitoring, retractors, blades, shims, and lighting equipment) may be a relevant consideration in determining a reasonable royalty under sixth Georgia-Pacific factor. See Infinity Comput. Prods., Inc. v. Epson Am., Inc., No. 18-cv-2532-RGK-RAOX, 2018 WL 7890859, at *2 (C.D. Cal. Dec. 14, 2018) (citing Trans-World Mfg. Corp. v. Al Nyman & Sons, Inc., 750 F.2d 1552, 1568 (Fed. Cir. 1984)) (“[T]he extent of the profits from such sales could be relevant in determining the amount of a reasonable royalty. If, for example, sales were increased because of the infringing use of the displays, that fact could affect the amount of royalties a potential licensee would be willing to pay.“).
Though much of the parties’ briefing focuses on whether the Accessory Products are in fact “functionally related” sufficient to recover damages based on a convoyed sales theory, the Court finds this question relates to admissibility, rather than discovery, and is
NuVasive maintains the motion should be denied because the interrogatory is vague, overbroad, and unduly burdensome. As a preliminary matter, the Court is not persuaded by NuVasive‘s argument that 4WEB did not sufficiently identify which specific products fall within its twelve categories of Accessory Products. The terminology appears consistent with NuVasive‘s references in its own materials and the expert report in Alphatec Holdings, Inc., No. 18-cv-347-CAB-MDD.
NuVasive primarily objects based on burden. NuVasive represents in its opposition, without a declaration or other evidentiary support, it “does not keep an electronic repository (such as a database) from which the requested data could be easily generated.” ECF No. 150 at 4. NuVasive also vaguely asserts answering the interrogatory “requires NuVasive to review invoices associated with over 80,200 transactions and then demands NuVasive produce a detailed financial accounting for products that happen to be included on the same invoice as an Accused Product.” Id. NuVasive further represents it “would have to pull and review invoices for each sale of an Accused Product to identify the Accessory Products (if any) sold with the Accused Product” and it “stores invoices in multiple repository systems and does not organize invoices by product type.” Id. at 11. NuVasive states, again without a declaration or other evidentiary support, its “IT
The Court finds NuVasive‘s unsupported and vague assertions do not satisfy its burden of supporting its objections. See Goro, 334 F.R.D. at 283; Licea, 2020 WL 1975059, at *1. Moreover, much of NuVasive‘s arguments focus on providing “detailed financial information” in response to the interrogatory. See ECF No. 150 at 4, 11. Relying on the representations from Counsel during the hearing that many of the Accessory Products identified by 4WEB may not be sold but instead provided to surgeons on a consignment basis and then returned to NuVasive, the Court finds it is not proportional to the needs of the case at this time—prior to production of the invoices of the Accused Products by NuVasive as discussed below—to require NuVasive to answer the detailed financial information sought by Interrogatory No. 6.
Rather, in light of NuVasive‘s representation during the May 7, 2025 hearing that many of the Accessory Products are provided on a consignment basis, the Court finds the invoices of the Accused Products are both relevant and proportional to the needs of the case. In assessing the relevant factors, the Court notes NuVasive has not put forward a less burdensome way to identify the Accessory Products sold with the Accused Products; rather, it‘s the Court‘s understanding based on NuVasive‘s representations in its briefing and during oral argument the invoices for the Accused Products are the only way to identify which Accessory Products, if any, were sold with the Accused Products. The Court has also considered NuVasive‘s alleged undue burden but finds NuVasive has not demonstrated this burden with any particularity, despite numerous opportunities to do so. Accordingly, the Court finds NuVasive‘s general claim of undue burden, without more, does not outweigh the likely benefit of the invoices. In addition, the Court finds numerous other proportionality factors weigh in favor of requiring production of the invoices for the Accused Products, including the amount in controversy, the parties’ relative access to information, and the importance of the invoices in identifying Accessory Products sold with the Accused Products.
For the reasons stated above, the Court GRANTS IN PART 4WEB‘s Motion to Compel as to Interrogatory No. 6. The Court ORDERS NuVasive to produce invoices for the Accused Products.
IT IS SO ORDERED.
