Independently Performed, Publicly Disclosed Prior Work Can Lead to Joint Inventorship

by | Jul 23, 2020 |

Addressing an inventorship decision that added two co-inventors to patents covering cancer treatments, the US Court of Appeals for the Federal Circuit agreed that the co-inventors’ work constituted joint inventorship even though it was performed independently and publicly disclosed prior to conception of the claimed invention. Dana-Farber Cancer Institute v. Ono Pharma. Co., Ltd., Case No. 19-2050 (Fed. Cir. July 14, 2020) (Lourie, J.).

In 2015, Dana-Farber filed an inventorship correction claim seeking to add two of its researchers as inventors to six patents covering cancer treatments that named inventors who had assigned the patents to Ono Pharmaceutical. After an eight-day bench trial, the district court judge issued a 111-page decision agreeing that Dana-Farber’s researchers were joint inventors for all six patents. Ono appealed.

Ono first argued that, as a matter of law, the contributions from Dana-Farber’s researchers were too far removed from the claimed invention because their contributions had been independently performed and publicly disclosed prior to conception, and thus constituted prior art to the patents. The Federal Circuit acknowledged that simply informing another inventor about the state of the prior art does not make one a joint inventor. However, the Court contrasted that situation with a genuine contribution by a participant in a collaborative enterprise that lasted over a year, where the contribution happened to be published shortly before conception. The Court stated that such a situation may be sufficient to lead to joint inventorship.

Ono also contested the district court’s factual determination that Dana-Farber’s researchers contributed to the invention as claimed. Specifically, Ono argued that the contributions from Dana-Farber’s researchers did not relate to the claimed subject matter of an antibody for a particular receptor. Dana-Farber responded that, as found by the district court, all six patents had the same core invention of blocking a particular ligand-receptor interaction and thus the identification of the relevant ligand by Dana-Farber’s researchers was properly considered part of the conception of all claims. The Federal Circuit agreed and affirmed the district court.

Delicate Balance: Details of Parallel Proceeding Tip Scales for Discretionary Denial

by | Jul 22, 2020 | ,

The Patent Trial and Appeal Board (Board) designated two decisions informative as they relate to weighing factors for determining how a parallel district court proceeding may impact the Board’s determination of whether to discretionarily deny institution under § 314(a).

In Apple Inc. v. Fintiv, Inc., Case No. IPR2020-00019, Paper 15 (USPTO May 13, 2020) (Horner, APJ) (designated informative on July 13, 2020), the Board had previously requested supplemental briefing in a pre-institution order in this case (itself now designated by the Board as precedential) regarding six factors for weighing the impact of the parallel district court proceeding on whether to discretionarily deny institution.

As to factor (1), whether the district court action is stayed or evidence exists that a stay may be issued, the Board weighed this factor as neutral because neither party had requested a stay and the district court had given no indication as to whether it would entertain a stay. Absent definitive statements by the district court as to the specific case, the Board declined to infer how a judge might rule if a motion were to be filed.

Under factor (2), the proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision, the Board found this factor weighed slightly in favor of a discretionary denial. Even though the district court’s initial trial date had been pushed back, the new date was still two months earlier than the Board’s one-year deadline for issuing a final written decision. In addition, the new date appeared to be relatively certain, and mere speculation about the further delays being typical was not enough to weigh this factor in favor of a discretionary denial.

As to factor (3), the court’s and parties’ investment in the parallel proceeding, the Board found this weighed somewhat in favor of discretionary denial. Even though expert reports had not been served, the district court had already issued a detailed Markman order construing seven claim terms, and the parties had already served their final invalidity contentions.

Under factor (4), the extent of overlap of the issues raised in the petition compared to those raised in the parallel proceeding, the Board found this factor favored discretionary denial because the Petitioner was pursuing the same prior art on the same claims in district court.

Under factor (5), the parties in the district court action were the same as the IPR, so this factor weighed in favor of discretionary denial.

As to the catch-all factor (6), including considering the merits of the challenge, the Board found that there were key weaknesses in the petition that helped tip the scales toward discretionary denial. In sum, the Board found that the weight of the factors tipped toward exercising its discretion to deny institution.

In Sand Revolution II, LLC v. Continental Intermodal Group–Trucking LLC, Case No. IPR2019-01393, Paper 24 (USPTO June 16, 2020) (Flax, APJ) (designated informative on July 13, 2020), the Board came to slightly different conclusions for some of the factors, ultimately granting the Petitioner’s request [...]

Joined Parties Have Rights Too

by | Jul 22, 2020 | ,

In vacating an unpatentability decision by the Patent Trial and Appeal Board (Board), the US Court of Appeals for the Federal Circuit found that the rights of a joined party to an inter partes review (IPR) proceeding applies to the entirety of the proceedings and includes the right of appeal. Fitbit, Inc. v. Valencell, Inc., Case No. 19-1048 (Fed. Cir. July 8, 2020) (Newman, J.).

Apple petitioned the Board for IPR of certain claims of a patent owned by Valencell. The Board granted the petition in part, instituting review of certain claims and denying review of other claims. After institution of the Apple IPR, Fitbit filed an IPR petition for the instituted claims and moved for joinder with Apple’s IPR. The Board granted Fitbit’s petition, granted the motion for joinder and terminated Fitbit’s separate proceeding.

After the Apple/Fitbit IPR hearing, but before any Final Written Decision was issued, the Supreme Court decided SAS Institute v. Iancu (IP Update, Vol. 21, No. 5), holding that the America Invents Act requires that all patent claims challenged in an IPR petition must be reviewed by the Board if the petition is granted. Accordingly, the Board re-instituted the Apple/Fitbit IPR to add the previously denied patent claims. The Board’s Final Written Decision found the originally instituted claims unpatentable, but the newly instituted claims not unpatentable. After the decision, Apple withdrew from the proceeding. Fitbit appealed the decision as to newly instituted claims that had been found not unpatentable.

On appeal, Valencell challenged Fitbit’s right to appeal as to the newly instituted claims. 35 U.S.C. § 319 provides that “[a]ny party to the inter partes review shall have the right to be a party to the appeal.” Valencell argued that Fitbit does not have the status of “party” for purposes of appeal because Fitbit did not request review of the newly instituted claims in its initial IPR petition, did not request leave to amend its initial petition after the Supreme Court’s decision in SAS Institute and did not submit a separate brief with respect to the non-instituted claims after the joined IPR was re-instituted. Valencell also argued that because the Board stated that Fitbit would have “limited participation, if at all, and required Fitbit to seek authorization from the Board before filing any papers,” Fitbit was not a full participant in the joined IPR.

Fitbit responded that Valencell did not object to Fitbit’s joinder and did not object to or seek to qualify Fitbit’s continued participation after the Board re-instituted the joined IPR to include the new claims, so there was only one IPR. Fitbit also cited the Board’s statement in granting its joinder motion that the “[d]ecision addressing the status of each challenged claim in this proceeding applies to all parties.” Fitbit acknowledged that it did not seek to file a separate brief after the new claims were added to the IPR, but claimed no separate brief was needed to present the issues.

The Federal Circuit agreed with Fitbit, finding that the circumstances [...]

Third Parties Not Responsible for Defective Motion to Seal

by | Jul 22, 2020 |

The US Court of Appeals for the Federal Circuit held that a district court did not abuse its discretion in denying reconsideration of a previous order denying a litigant’s defective motion to seal  with regard to the litigant’s own information, but vacated and remanded for further consideration with regard to third-party information. Uniloc 2017 LLC v. Apple, Inc., Case Nos. 19-1922, -1923, -1925, ‑1926 (Fed. Cir. July 9, 2020) (Mayer, J.).

Uniloc sued Apple for patent infringement in the Northern District of California. Apple moved to dismiss. The briefing on the motion included material that Uniloc had designated as highly confidential. Both parties filed motions to seal. Uniloc’s motions to seal covered quotations from published opinions and matters of public record, among other things. Uniloc’s supporting declarations included only boilerplate assertions of harm from disclosure. Non-party Electronic Frontier Foundation asked Uniloc to narrow its redactions, and when Uniloc declined, Electronic Frontier moved to intervene for the purpose of opposing Uniloc’s sealing motions. The district court denied the motions to seal as overbroad under the local rules, which require such motions to be narrowly tailored.

Uniloc sought an extension of time and ultimately filed a motion for leave to seek reconsideration. In that motion, it agreed to make public more than 90% of the material it had originally sought to seal. It also filed a new motion to seal the remainder. In support, it attached a much more specific declaration supporting sealing the more limited set of materials, as well as several declarations of third-party licensees, who stated that disclosure of their confidential information would be harmful to them. The court denied the motion seeking leave as not meeting the local rules’ requirements for reconsideration. The court also denied the narrower motion to seal, reasoning that Uniloc should have filed a proper motion to seal in the first instance. Uniloc appealed.

Uniloc argued that the district court had abused its discretion in denying the narrower motion to seal. In considering Uniloc’s argument, the Federal Circuit distinguished between Uniloc’s information and third-party information. Applying Ninth Circuit law, the Court held that the district court had not abused its discretion by strictly enforcing its local rules with regard to Uniloc’s information. Uniloc had violated the local rules in its motion to seal and subsequent motion for reconsideration. Moreover, the Court explained that notwithstanding the submission of a narrowly tailored motion, the burden is always on the moving party to provide compelling reasons for sealing, which Uniloc had failed to do.

Next, the Federal Circuit explained that third-party information “calls for an analysis not dependent on the overbreadth rationale” because third parties should not be harmed by a litigant’s failure to follow the local rules. Because the district court’s analysis had been based on overbreadth, the Court found that the district court “failed to make findings sufficient to allow us to adequately assess whether it properly balanced the public’s right of access against the interests of the third parties in shielding their . .

Technical Issues Affirm Patent Validity but Preclude Pre-Suit Damages

by | Jul 22, 2020 |

In a split decision, the US Court of Appeals for the Federal Circuit affirmed the subject matter eligibility of claims directed to collection, comparison and classification of information. The Court also unanimously found that the patent owner was not entitled to pre-suit or enhanced damages because it failed to prove pre-suit patent marking by its licensees. Packet Intelligence LLC v. Netscout Systems, Inc., Case No. 19-2041 (Fed. Cir. July 14, 2020) (Lourie, J.) (Reyna, J., dissenting in part).

This dispute began when Packet Intelligence sued Netscout for infringing three of its patents that were directed to a system and method for monitoring packets exchanged over a computer network. The case was tried before a jury, which found the patents-in-suit valid and infringed. The jury further determined that Packet Intelligence was entitled to pre-suit and post-suit damages, as well as enhanced damages. Netscout filed a motion for judgment as a matter of law that Packet Intelligence was not entitled to pre-suit damages, which the district court denied. Following a bench trial, the district court held that the claims of the patents-in-suit were not invalid under 35 USC § 101. Netscout appealed.

Netscout challenged the district court’s § 101 decision and the denial of Netscout’s motion for judgment as a matter of law on pre-suit damages. In a split panel decision, the Federal Circuit affirmed the district court’s determination on subject matter eligibility under § 101. Netscape specifically argued that the claims were directed to an abstract idea because the claims were merely directed to the collection, comparison and classification of information.

The majority reiterated that the Federal Circuit has recognized that software-based innovations may be deemed patent-eligible subject matter at Alice step 1. For example, in Enfish, the Court held that software claims were valid at step 1 because the claims were directed to a technical improvement over conventional systems. Similarly, in SRI International, the Court held that software claims were valid because the claims at issue were “necessarily rooted in computer technology in order to solve a specific problem in the realm of computer networks.” Applying these principles, the majority found that the claims were patent eligible because they presented a technical solution to a technical problem. Notably, the majority relied on the patent specification’s disclosures regarding the invention’s improvements over conventional systems.

Judge Reyna dissented. In his view, the claims were directed to an abstract idea because they lacked specific technological means for the collection, analysis and display of data. Because a concrete technical solution was absent, Reyna argued that the claims were distinguishable from the SRI International case on which the majority relied. He would have found the claims invalid under step 1 and remanded the case to the district court to fully address Alice step 2.

Regarding pre-suit damages, the Federal Circuit unanimously held that Packet Intelligence was not entitled to such damages. The primary issue was whether a Packet Intelligence licensee had properly complied with the marking requirements in order to provide the required constructive notice to [...]

Patent Owners Beware: Serial Filings, Rent-Seeking May Be Grounds for Adverse Fee Award

by | Jul 15, 2020 |

The US Court of Appeals for the Federal Circuit vacated and remanded a district court’s denial of attorney’s fees to an accused infringer, finding the district court did not properly consider the Patent Owner’s manner of litigation, including the history of plaintiff’s actions in other jurisdictions and the broader context of its litigation practices. Elec. Commc’n Techs., LLC v. ShoppersChoice.com, LLC, Case No. 19-2087 (Fed. Cir. July 1, 2020) (Wallach, J.).

Following a finding by a Florida district court that a patent asserted by Electronic Communication Technologies (ECT) was ineligible under 35 U.S.C. § 101, ShoppersChoice filed a motion for attorney’s fees, citing ECT’s use of standardized demand letters and repeated infringement actions seeking nuisance-value settlements. ShoppersChoice also informed the district court of a recent award of attorney’s fees against ECT in the Central District of California (the True Grit decision) for conduct relating to the same asserted patent. The district court denied ShoppersChoice’s motion, finding that the case was not exceptional and that ECT’s litigation position was not so obviously weak. ShoppersChoice appealed.

The Federal Circuit reviewed the district court’s denial of attorney’s fees under the abuse of discretion standard, analyzing whether the district court made “a clear error of judgment in weighing relevant factors or in basing its decision on an error of law or on clearly erroneous factual findings” and whether it provided a “concise but clear explanation of its reason[ing].” The Court explained that “a pattern of litigation abuses characterized by the repeated filing of patent infringement actions for the sole purpose of forcing settlements, with no intention of testing the merits of one’s claims, is relevant to a district court’s exceptional case determination under § 285.” The Court found that the district court failed to conduct this analysis and erred by not considering ECT’s manner of litigation and the broader context of ECT’s litigation practices. Addressing the True Grit decision, the Federal Circuit noted that the California district court provided a detailed account of the nuisance value rent-seeking practices of ECT (and other affiliated shell companies), but ultimately found that the court failed to conduct an adequate inquiry into ECT’s litigation conduct.

The Federal Circuit thus vacated the attorney’s fee award and remanded the case, directing the district court to consider both ECT’s manner of litigation and the objective unreasonableness of its claims.

Practice note: While the California District Court’s decision is not binding in the Florida court, the Federal Circuit made clear that a court cannot ignore developments in other jurisdictions in connection with § 285 fee determinations.

“All Substantial Rights” Test Informative in Obviousness-Type Double Patenting Context

by | Jul 15, 2020 |

The US Court of Appeals for the Federal Circuit endorsed for the first time the “all substantial rights” test to determine whether inventions are commonly owned for purposes of obviousness-type double patenting validity analysis of a later patent. Immunex Corp. v. Sandoz, Inc., Case No. 20-1037 (Fed. Cir. July 1, 2020) (O’Malley, J.) (Reyna, J., dissenting). The Court determined that patents were not commonly owned—and therefore a later patent was not invalid for obviousness-type double patenting—when the patentee retained a secondary right to sue for infringement and the right to “veto” further assignment of the patents by the grantee.

Roche licensed a family of patent applications to Immunex. Under the license agreement, Immunex agreed to pay a running royalty to Roche based on sales of products incorporating the patented technology. Non-party Amgen subsequently acquired Immunex. Amgen, Immunex and Roche entered into an agreement to eliminate the continuing royalties to Roche. The agreement granted to Immunex a paid-up, irrevocable, exclusive license to the US patent family for the patents-in-suit and gave Immunex the sole right to sublicense. It further granted Immunex the exclusive right to prosecute applications in the US patent family. Critically, Roche retained the secondary right to assert the patents if Immunex did not assert them in litigation after being informed of potential infringement, and the right to veto any downstream assignment by Immunex to a third party.

Immunex and Roche later sued Sandoz for infringing a patent included in the license agreement. At trial, Sandoz argued that the patents-in-suit were invalid for obviousness-type double patenting over several patents filed by Immunex.

The judicially created doctrine of obviousness-type double patenting prohibits claims in a second patent that, while not for the same invention, are so similar to the claims of a commonly owned earlier patent that granting both patents exclusive rights would “effectively extend the life of patent protection.” This doctrine rests primarily on two justifications: preventing unjustified extension of the time of the right to exclude, and preventing multiple infringement suits by different assignees. The doctrine applies to all commonly owned patents, including cases in which the obvious variant inventions have different inventors.

Urging a novel theory of common ownership, Sandoz argued that although the patents-in-suit were assigned to Roche, Immunex effectively owned both the Immunex patents and the patents-in-suit. Sandoz asserted that the agreement between Amgen, Immunex and Roche conveyed “all substantial rights” in the patents-in-suit, which was tantamount to an assignment of ownership. Thus, Sandoz argued that the “all substantial rights” test, which previously had only been used to determine who had standing to sue for infringement as a “patentee” under 35 USC § 281, should apply in the context of obviousness-type double patenting.

Immunex argued that the “common ownership” analysis should take into account ownership at the time of invention, such that common-ownership-based obviousness-type double patenting arises only where the relevant inventions were owned by the same entity.

The Federal Circuit agreed with Sandoz, endorsing for the first time the all substantial rights test to [...]

Federal Circuit Extends Arthrex to Ex Parte Re-Examination Proceedings

by | Jul 15, 2020 |

The US Court of Appeals for the Federal Circuit vacated and remanded a decision issued by the Patent Trial and Appeal Board (PTAB), holding that its decisions in Arthrex and VirnetX also apply to ex parte examinations at the PTAB. In re: Boloro Global Ltd., Case Nos. 19-2349, -2351, -2353 (Fed. Cir. July 7, 2020) (Dyk, J.).

The issue regarding ex parte appeals started to take shape in October 2019—in the context of an inter partes review (IPR) proceeding—when the Federal Circuit held that the appointment of administrative patent judges (APJs) at the PTAB is unconstitutional. Arthrex v. Smith & Nephew (IP Update, Vol. 22, No. 11). APJs are appointed by the secretary of commerce in consultation with the director of the US Patent and Trademark Office (PTO) pursuant to 35 USC § 6(a). In Arthrex, The Federal Circuit determined that APJs are principal officers and are not constitutionally appointed, because as principal officers they must be appointed by the president with the advice and consent of the Senate.

Having concluded that the appointment of APJs violated the Appointments Clause, the Federal Circuit held that “where the final decision was rendered by a panel of APJs who were not constitutionally appointed,” and “where the parties presented an Appointments Clause challenge on appeal,” the decision below “must be vacated and remanded.” The Court further instructed that, on remand, a new panel of APJs must be designated and a new hearing granted. The Court put a bookend on its holding, ruling that where an Appointment Clause challenge was not raised in an opening brief, the challenge was waived. So PTAB decisions that issued before Arthrex, if timely appealed and subject to an Appointment Clause challenge in the opening brief, could be vacated as unconstitutional and remanded for a new panel of APJs.

In May 2020, the Federal Circuit extended its decision in Arthrex to final decisions issued by APJs in inter partes re-examination proceedings (VirnetX v. Cisco Systems). In VirnetX, the Court discerned no differences between the duties of an APJ in an IPR proceeding as compared to an inter partes examination proceeding, because both proceedings involve third-party challenges to an issued patent and in both proceedings APJs exercise significant authority by issuing final decisions that decide the patentability of the challenged claims, and the PTO director does not have an independent way of reviewing those final determinations.

The present case arose in the context of an appeal from an examiner in ex parte prosecution. Boloro argued that APJs in ex parte appeals also exercise significant authority by virtue of the matters on which they are asked to render judgment, and carry out similar functions when they carry out their function of deciding IPRs. Boloro asserted that although ex parte appeals were not specifically addressed in Arthrex, the PTAB also has the power in ex parte appeals to disqualify counsel, to admit people pro hac vice, and to order appellants to additionally brief any matter that the PTAB considers to [...]

Stick to Your Guns: PTAB Should Rarely Issue New Grounds of Unpatentability

by | Jul 15, 2020 |

The Patent Trial and Appeal Board (PTAB) Precedential Opinion Panel (POP) issued a precedential opinion in an inter partes review (IPR) to resolve two questions:

  • May the PTAB raise a ground of unpatentability not developed by the petitioner?
  • If it does so, must the PTAB provide the parties notice and an opportunity to respond to the new ground of unpatentability?

Hunting Titan, Inc. v. DynaEnergetics Europe GmbH, Case No. IPR2018-00600 (USPTO July 6, 2020) (Boalick, CAPJ) (granting request for POP rehearing). The POP held that while the PTAB may raise new grounds of unpatentability, it should refrain from doing so except in rare instances. If it does raise new grounds of unpatentability, the PTAB must provide the parties notice and an opportunity to respond to the new grounds.

Titan filed a petition requesting IPR of a patent owned by DynaEnergetics directed to a perforating gun assembly for wellbore tools. One of the grounds alleged anticipation by a prior art reference (Schacherer). The PTAB instituted review, and DynaEnergetics timely moved to amend the claims. Opposing the motion to amend, Titan argued that the substitute claims were obvious over various prior art references, including the Schacherer reference. Titan did not argue anticipation as to the substitute claims. In its final written decision, the PTAB held that the amended claims were unpatentable because they were anticipated by Schacherer. DynaEnergetics moved for reconsideration and POP review.

The POP granted review to provide precedential guidance on new grounds of unpatentability. Citing to the recent US Court of Appeals for the Federal Circuit decision in Nike, Inc. v. Adidas AG, the POP determined that the PTAB may raise new grounds of unpatentability in certain cases, but those cases should be exceedingly rare. The POP reasoned that the adversarial nature of an IPR proceeding puts the competing parties in a better position to identify and argue the strongest grounds. The POP rejected the notion that the PTAB should independently examine the patentability of every proposed substitute claim, as if it were a reexamination proceeding, by culling through the prior art to determine if better unpatentability arguments could have been presented. Only in rare cases that are no longer adversarial, such as when a petitioner does not oppose a motion to amend or when a petitioner ceases to participate in an instituted IPR that proceeds to a final judgment, would it be reasonable for the PTAB to consider new grounds of unpatentability. Although the POP did not articulate every exceptional scenario, it suggested that when the record “readily and persuasively” establishes that substitute claims are unpatentable, it would be reasonable for the PTAB to rely on a new ground of unpatentability. Titan’s IPR was not an exceptional case, so the POP reversed the panel’s decision as to the substitute claims.

The POP also explained that the parties must be given notice and an opportunity to respond to any new grounds the PTAB may raise. With respect to substitute claims, notice cannot come from the grounds [...]
