8 Plaintiffs, ORDER REQUIRING PLAINTIFF TO 9 v. SERVE AMENDED INFRINGEMENT CONTENTIONS Re: Dkt. No. 192 Defendant. 11

12 13 In this consolidated action, plaintiffs AbCellera Biologics Inc. and The University of 14 British Columbia (collectively, “AbCellera”) allege infringement of fifteen patents.1 The asserted 15 patents are generally directed to methods that use microfluidics in cell analyses. See Dkt. No. 164. 16 Defendant Bruker Cellular Analysis (“Bruker Cellular”) now moves for an order striking 17 AbCellera’s amended infringement contentions, arguing that AbCellera’s contentions do not 18 comply with Patent L.R. 3-1. Dkt. No. 192. AbCellera opposes the motion. Dkt. No. 209. Upon 19 consideration of the moving and responding papers, as well as the arguments presented at the 20 February 20, 2024 hearing, the Court orders AbCellera to serve amended infringement contentions 21 that comply with the Court’s direction below. 23 On March 31, 2021, AbCellera served its Patent Local Rule 3-1 disclosures, including 24 infringement contentions regarding seven accused instrumentalities. Dkt. No. 192 at 1-2. On 25 November 2, 2023, AbCellera served amended Patent Local Rule 3-1(b) disclosures, identifying 26 1 U.S. Patent Nos. U.S. Patent Nos. 10,087,408; 10,107,812; 10,274,494; 10,421,936; 10,466,241; 27 10,578,618; 10,697,962; 10,704,018; 10,718,768; 10,738,270; 10,746,737; 10,753,933; 1 many additional accused instrumentalities.2 Id. at 2-3. 2 On December 29, 2023, AbCellera served amended disclosures of asserted claims and 3 infringement contentions directed to asserted claims in seven patents. Id. at 3, 7. The amended 4 infringement contentions purport to incorporate both AbCellera’s original March 31, 2021 Patent 5 Local Rule 3-1 disclosures and its November 2, 2023 amended Patent Local Rule 3-1(b) 6 disclosures. Dkt. No. 192-1, Ex. B & Exs. 1-7. That is, AbCellera’s December 29, 2023 amended 7 infringement contentions supplement, but do not replace, AbCellera’s earlier disclosures. Id. 8 Although AbCellera identifies several accused instrumentalities, its contentions are presented in a 9 single chart for each asserted patent. Id. 11 Among other things, Patent Local Rule 3-1 requires “a party claiming patent infringement” 12 to identify for each asserted claim “each accused apparatus, product, device, process, method, act, 13 or other instrumentality . . . of which the party is aware.” Patent L.R. 3-1(b). This identification 14 must be “as specific as possible,” including “by name or model number, if known.” Id. “[A]ll 15 courts agree that the degree of specificity under [Patent] Local Rule 3-1 must be sufficient to 16 provide reasonable notice to the defendant why the plaintiff believes it has a ‘reasonable chance of 17 proving infringement.’” Shared Memory Graphics LLC v. Apple, Inc., 812 F. Supp. 2d 1022, 18 1025 (N.D. Cal. 2010) (quoting View Eng’g, Inc. v. Robotic Vision Sys., Inc., 208 F.3d 981, 986 19 (Fed. Cir. 2000)). The Patent Local Rules do not “require the disclosure of specific evidence nor 20 do they require a plaintiff to prove its infringement case,” but “a patentee must nevertheless 21 disclose what in each accused instrumentality it contends practices each and every limitation of 22 each asserted claim to the extent appropriate information is reasonably available to it.” DCG Sys. 23 v. Checkpoint Techs., LLC, No. 11-cv-03792-PSG, 2012 WL 1309161, at *2 (N.D. Cal. Apr. 16, 24 2012) (internal quotations and citation omitted). 25 “Striking a patentee’s infringement contentions is a severe sanction that should be used 26

27 2 By separate order, the Court grants Bruker Cellular’s motion to strike new accused products with 1 sparingly and only for good cause.” Avago Techs., Inc. v. IPtronics Inc., No. 10-cv-02863-EJD, 2 2015 WL 4647923, at *2 (N.D. Cal. Aug. 5, 2015) (citation omitted). As a result, “motions to 3 strike initial infringement [contentions] are frequently treated as motions to compel amendment of 4 the infringement contentions.” Geovector Corp. v. Samsung Elecs. Co., No. 16-cv-02463-WHO, 5 2017 WL 76950, at *7 (N.D. Cal. Jan. 9, 2017). 7 Bruker Cellular moves to strike AbCellera’s amended infringement contentions on several 8 grounds. The Court addresses the parties’ arguments with respect to each ground. 9 A. Whether the Amended Contentions Disclose How the Accused Instrumentalities Infringe the Claimed Methods 10 11 Observing that all of the asserted claims at issue are method claims, Bruker Cellular argues 12 that AbCellera’s contentions do not provide reasonable notice of how the accused instrumentalities 13 practice each limitation of the claimed methods. According to Bruker Cellular, the contentions 14 focus almost exclusively on the components of the accused Beacon systems, with no explanation 15 of how those systems are used to perform each step of each claimed method. Dkt. No. 192 at 7-9. 16 In addition, Bruker Cellular complains that while AbCellera’s contentions quote extensively from 17 Bruker Cellular’s technical documentation, the contentions do not actually explain or describe 18 how any accused instrumentality infringes. Id. at 11-16. 19 AbCellera responds that its contentions provide sufficient notice of its infringement 20 theories because they “make clear that use of the accused systems and supporting technologies in 21 performance of the accused workflows practice the claimed methods.” Dkt. No. 209 at 16.3 22 AbCellera notes that its contentions quote in detail and at length from Bruker’s Cellular’s own 23 documents and that those documents use many of the same terms that appear in the asserted 24 claims. Id. at 16-18. AbCellera argues that it would be premature to require further elaboration of 25 its infringement theories before the Court issues a claim construction order. See id. at 20. 26 3 AbCellera complains that Bruker Cellular has not produced technical documents sufficient to 27 show the operation of all accused instrumentalities, but AbCellera argues, that despite this 1 The Court agrees with Bruker Cellular that AbCellera’s amended infringement contentions 2 do not provide reasonable notice of how the accused instrumentalities practice each limitation of 3 the claimed methods. For each such limitation, AbCellera must identify “where and how” the 4 limitation is found. Patent L.R. 3-1(c). Because method claims are infringed only when the 5 method is performed, see Joy Techs., Inc. v. Flakt, Inc., 6 F.3d 770, 774-75 (Fed. Cir. 1993), 6 AbCellera must disclose more than a system that is “capable of” performing the patented methods. 7 More importantly, AbCellera must actually disclose what its contentions are; it may not rely 8 exclusively on inferences that must be drawn from materials cited or quoted in the contentions. 9 AbCellera is correct that the claimed methods are methods for using a system and its 10 components, and that its contentions necessarily identify those systems and components. But 11 simply identifying the systems and components is not sufficient. For example, showing the 12 existence of a “cell” in a “chamber” does not fully address the first limitation of claim 1 of the 13 ’408 patent, which requires “retaining the cell at a retaining position within an individual chamber 14 of a microfabricated device.” Similarly, identifying how an accused instrumentality meets the 15 second limitation of claim 1 of the ’408 patent—“perfusing the cell with a perfusion fluid by 16 flowing the perfusion fluid into the individual chamber though an inlet and out of the chamber 17 through an outlet, wherein the outlet is positioned such that gravitational forces acting on the cell 18 to keep it at or near the retaining position exceed hydrodynamic forces acting on the cell to move 19 it toward the outlet”—requires the patentee to identify not only where the “chamber,” “inlet,” and 20 “outlet” are found in the system, but also how the accused use of the system results in “flowing the 21 perfusion fluid into the individual chamber through an inlet and out of the chamber through an 22 outlet.” Dkt. No. 164-1 at ECF 289. 23 The principal difficulty with AbCellera’s amended infringement contentions is that they 24 fail to give reasonable notice of what AbCellera’s infringement theory is for each asserted claim. 25 Showing that the same words appear in the claims and in Bruker Cellular’s technical documents 26 carries only so much water; if the basis for the alleged infringement cannot be easily inferred from 27 the juxtaposition of the claim language and the cited material in a claim chart, a patentee must do 1 any of the cited material, AbCellera’s pattern-matching approach necessarily falls short. While 2 AbCellera’s contentions do indeed include extensive citations to and quotations from Bruker 3 Cellular’s documents, in most instances it is not self-evident how AbCellera believes Bruker 4 Cellular (or users of Bruker Cellular’s systems) practices each limitation of each claimed method.4 5 AbCellera is not required to prove infringement at this stage, but it must make its 6 infringement contentions explicit. It may not simply quote or paraphrase the claim language, as it 7 has done for each of the limitations, but must instead state where and how each limitation is found 8 in the accused instrumentalities. There is nothing premature about this requirement. The Patent 9 Local Rules require the patentee to disclose its infringement contentions and the accused infringer 10 to disclose its invalidity contentions before the parties disclose their respective claim construction 11 positions. See Patent L.R. 3-1, 3-3, 4-1. While AbCellera need not anticipate every possible 12 claim construction, the Court agrees with Bruker Cellular that AbCellera must disclose at least one 13 infringement theory based on at least one claim construction for each accused instrumentality, see 14 Dkt. No. 212 at 7, and may not simply “wait and see” how the Court ultimately construes disputed 15 claim terms. 16 B. Whether the Amended Contentions Comply with the Requirements of Patent Local Rule 3-1(c) to Separately Chart Each Accused Instrumentality 17 18 Bruker Cellular argues that AbCellera’s contentions do not comply with Patent Local Rule 19 3-1(c), which requires “[a] chart identifying specifically where and how each limitation of each 20 asserted claim is found within each Accused Instrumentality,” because the contentions rely on a 21 single claim chart for all accused instrumentalities. Dkt. No. 192 at 9-11. AbCellera responds that 22 the accused Beacon systems can be used in combination with “various OptoSelect® chips and 23 other supporting technologies to perform Defendant’s workflows,” and that the contentions do not 24 mix and match features of distinct accused instrumentalities. Dkt. No. 209 at 19. 25 Based on the discussion at the hearing, the Court understands that the three accused 26

27 4 Indeed, when the Court asked AbCellera’s counsel to explain one of AbCellera’s infringement 1 Beacon systems are not materially distinct as relevant to AbCellera’s infringement theories. While 2 it appears to be undisputed that there are differences between and among the chips and workflows 3 that may be used with these systems, see Dkt. No. 216 at 62:10-65:11, the parties disagree 4 vigorously whether those differences matter for purposes of AbCellera’s infringement contentions, 5 see id. at 73:9-78:15. 6 The Court is not persuaded that AbCellera has adequately complied with the requirement 7 of Patent Local Rule 3-1(c) to provide “a chart . . . for each Accused Instrumentality.” Assuming 8 that an “accused instrumentality” is a workflow performed using a Beacon system and a chip, 9 AbCellera must separately chart each such distinct infringing combination. While it may be 10 permissible to group like systems (e.g., all three Beacon systems), like workflows (e.g., the Opto 11 Plasma B Discovery Workflows), and like chips (if any) in a single chart, AbCellera may not lump 12 all accused systems, workflows, and chips together in a single chart for each asserted patent, 13 leaving Bruker Cellular to figure out which combinations are accused. Rather, AbCellera must 14 separately chart distinct infringing combinations, and if the chart relies on groupings of like 15 systems, workflows, or chips, the chart must make this clear. 16 C. Whether the Amended Contentions Comply with the Requirements of Patent Local Rule 3-1(e) 17 18 Bruker Cellular argues that, with one exception, AbCellera’s contentions rely on generic 19 placeholder language regarding infringement under the doctrine of equivalents that does not 20 comply with Patent Local Rule 3-1(e). Dkt. No. 192 at 16-17. AbCellera responds that it has 21 adequately disclosed its doctrine of equivalents contentions by citing to and quoting from Bruker 22 Cellular’s technical documents. Dkt. No. 209 at 21-23. 23 With the exception of AbCellera’s disclosure regarding the “1,600 to 20,000 microfluidic 24 chambers” limitation, which appears in the ’936 patent and in the ’270 patent, AbCellera’s 25 doctrine of equivalents contentions fall short of what Patent Local Rule 3-1(e) requires. Although 26 that rule states that a patentee must disclose “[w]hether” a limited is present under the doctrine of 27 equivalents, courts in this District have required a patentee to do more than simply recite, for every 1 e.g., Geovector, 2017 WL 76950, at *7-8 (striking doctrine of equivalents contentions); Dynetix 2 Design Sols., Inc. v. Synopsys, Inc., No. 11-cv-5973 PSG, 2013 WL 4537838, at *1 (N.D. Cal. 3 Aug. 22, 2013) (“Even though the magic ‘function, way, result’ words are not specifically 4 required, a party looking to rely on equivalents still has to describe how these requirements are 5 met. Boilerplate is not enough.”). 6 Here, with the one exception noted above, AbCellera fails to provide any explanation for 7 why any limitation of any asserted claim is met under the doctrine of equivalents. Merely citing to 8 or quoting from Bruker Cellular’s technical documents, without more, is insufficient disclosure. If 9 AbCellera cannot articulate a basis for a doctrine of equivalents contention, it must remove the 10 “and equivalents thereof” language from the contention. 11 D. Whether the Amended Contentions Comply with the Requirements of Patent Local Rule 3-1(f) 12 13 Bruker Cellular argues that AbCellera should not be permitted to rely on contentions that 14 disclose a priority date described as “no later than X,” but must instead assert a specific priority 15 date. Dkt. No. 192 at 18-19. AbCellera argues that it has fully complied with its disclosure 16 obligations because it “incorporated by reference responses to interrogatories concerning 17 conception and reduction to practice, and produced documents evidencing the conception and 18 reduction to practice of the claimed inventions[.]” Dkt. No. 209 at 24. 19 Patent Local Rule 3-1(f) requires a patentee to disclose “[f]or any patent that claims 20 priority to an earlier application, the priority date to which each asserted claim allegedly is 21 entitled.” Patent L.R. 3-1(f). Here, AbCellera asserts that the priority date of each asserted claim 22 is “no later than” July 7, 2010 or July 16, 2010, depending on the patent family. This contention 23 does not comply with Patent Local Rule 3-1(f) which requires a patentee to take a position with 24 respect to the earliest priority application on a claim-by-claim basis. See Blue Spike, LLC v. 25 Adobe Sys., Inc., No. 14-cv-01647-YGR(JSC), 2015 WL 335842, at *7 (N.D. Cal. Jan. 26, 2015) 26 (Rule 3-1(f) “requires a patentee to assert a particular date—not a start date, end date, or date 27 range.”). This disclosure does not depend on any issue of conception or reduction to practice, but 1 priority. 2 Accordingly, AbCellera may not rely on a “not later than” date, but must instead identify a 3 specific priority date for each asserted claim. 4 || Iv. CONCLUSION 5 As explained above, the Court finds Bruker Cellular’s arguments persuasive. However, 6 || instead of striking AbCellera’s infringement contentions, the Court orders AbCellera to amend its 7 contentions to address the deficiencies described above. By separate order, the Court has granted 8 || Bruker Cellular’s motion to strike new accused products AbCellera’s amended Patent Local Rule 9 || 3-1(b) disclosures. Accordingly, AbCellera’s amended infringement contentions shall also be 10 || limited to the accused instrumentalities permitted by that separate order. 11 AbCellera’s amended Patent Local Rule 3-1 disclosures, including its amended contentions 12 under subsections (c), (e), and (f), must be served by April 8, 2024. || Dated: March 18, 2024
