Don’t Tread on Illinois’ Absolute Litigation Privilege

by | Oct 17, 2024 |

Addressing when Illinois law’s “absolute litigation privilege” bars certain counterclaims, the US Court of Appeals for the Federal Circuit affirmed a district court’s summary judgment finding that the plaintiff lacked a valid trade dress and reversed the district court’s decision that declined to apply the absolute litigation privilege as a complete defense to all of the alleged infringer’s counterclaims. Toyo Tire Corp v. Atturo Tire Corp., Case No. 22-1817 (Fed. Cir. Oct. 4, 2024) (Moore, Clevenger, Chen, JJ.) (nonprecedential).

Toyo and Atturo are competitors in the tire design business. After perceiving widespread copying of its tire designs, Toyo filed a district court action asserting design patent infringement and trade dress infringement against Atturo. Atturo asserted counterclaims, including false designation of origin under the Lanham Act and several state law counterclaims. The district court eventually dismissed with prejudice Toyo’s design patent infringement claims and proceeded with just the trade dress infringement claim.

A primary issue in the case was the description of the asserted trade dress. In its complaint, Toyo identified its trade dress merely as “the overall appearance” of its line of tires. Over the course of discovery, disputes arose concerning Toyo’s failure to distinctly describe its asserted trade dress. Toyo answered an interrogatory that requested this information with a non-limiting definition. The district court compelled Toyo to provide a more specific answer, which Toyo did by providing highlighted images.

Toyo’s fact witness was subsequently deposed under Fed. R. Civ. P. 30(b)(6) and gave answers that were inconsistent with Toyo’s interrogatory response. This led the district court to compel more testimony on what exactly the asserted trade dress contained, and which tire features met the definition of the trade dress, and which did not. On the advice of counsel, the corporate witness declined to answer more than 100 different questions. Toyo’s inability to describe its trade dress continued into expert discovery. When it served its expert reports, Toyo introduced yet another aspect of its trade dress – that the trade dress only included two-dimensional aspects. Toyo introduced this new argument to support the requirement that to qualify as trade dress the designated feature must be nonfunctional.

Atturo moved for sanctions. In granting the sanctions, the district court barred Toyo from asserting only the two-dimensional aspects of the trade dress, precluding Toyo from continually shifting its position because doing so “would effectively lead to trial by ambush.” Having struck the only argument that could save the trade dress from invalidity, the district court granted summary judgment of invalidity on both functionality and lack of secondary meaning.

Trial then proceeded only on Atturo’s counterclaims. The jury returned a verdict in favor of Atturo on six of the counterclaims, awarding $10 million in compensatory damages and $100 million in punitive damages. The district court set aside the jury verdict as it related to counterclaims of defamation and liability under the Illinois Deceptive Trade Practices Act. Both parties appealed.

The Federal Circuit affirmed the district court’s issuance of discovery sanctions, and the grant of [...]

No Matter How You Slice and Dice It, Conclusory Evidence Can’t Support Entire Market Value Damages

by | Oct 10, 2024 |

The US Court of Appeals for the Federal Circuit concluded that the entire market value rule was not applicable where conclusory expert testimony was the only evidence that a product’s infringing features drove consumer demand, and therefore reversed. Provisur Techs., Inc. v. Weber, Inc., Case No. 23-1438 (Fed. Cir. Oct. 2, 2024) (Moore, C.J.; Taranto, Cecchi, JJ.)

Provisur sued Weber in the Western District of Missouri over three patents related to slicing and packaging meats and cheeses. The jury determined that Weber willfully infringed several claims of the three asserted patents and awarded damages. Following the trial, Weber moved for judgment as a matter of law (JMOL) on the issues of infringement and willfulness, and a new trial on infringement, willfulness, and damages. The district court denied Weber’s motion in its entirety. Weber appealed.

The Federal Circuit affirmed the district court’s judgment with respect to two of the asserted patents but reversed the infringement finding on the sole asserted claim of the third patent. Provisur’s infringement theory was that the consumer could program the device to infringe the limitations of the claim. However, at trial, Provisur provided no evidence that it was actually possible for the consumer to configure the device to practice the claim or that any consumer had ever done so. Some of the software necessary to be configured in an infringing manner was not accessible to the consumer. Instead, only Weber service technicians could access it. Provisur also proffered no evidence that the devices had ever actually been configured to infringe the claims, instead only offering evidence that the claims could have been infringed.

Next, the Federal Circuit assessed willfulness. Weber’s primary argument was that the district court improperly allowed expert testimony in violation of 35 U.S.C. § 298, which states that a party’s failure “to obtain the advice of counsel with respect to any allegedly infringed patent . . . may not be used to prove that the accused infringer willfully infringed the patent.” Provisur’s expert, who testified about industry standards for intellectual property management, “did not distinguish between legal and non-legal services when testifying about consulting a third party.” The Court concluded that that portion of the testimony was inadmissible and the remaining evidence could not support a finding of willfulness.

Finally, the Federal Circuit addressed the damages issue, specifically focusing on the reasonable royalty award. The infringing features were subparts of a larger accused product – which had many non-infringing features. The accused product contained multiple separate machines unrelated to the alleged invention.

Provisur’s royalty award was predicated on its use of the entire market value rule, where the base to which the royalty rate is applied is the cost of the entire accused product as opposed the cost of just the infringing part. The Federal Circuit noted that the entire market value rule is an acceptable theory, but it requires a showing that the infringing part “is the basis for customer demand.”

Provisur’s damages expert used the entire market value rule in calculating the [...]

Got Pillaged? Not If You Didn’t Follow the APA and FTCA

by | Oct 10, 2024 |

The US Court of Appeals for the Federal Circuit affirmed a district court decision dismissing claims under the Administrative Procedure Act (APA) and Federal Tort Claims Act (FTCA) against the US Patent & Trademark Office (PTO) relating to “pillaged patents.” The Federal Circuit found that dismissal was appropriate because the plaintiff failed to exhaust administrative remedies and the claims were barred under collateral estoppel. Winfrey v. Dep’t of Com., Case No. 24-1260 (Fed. Cir. Sept. 25, 2024) (Prost, Hughes, Cunningham, JJ.) (per curiam).

Eula Winfrey filed a pro se complaint in district court seeking “relief for the issue of two pillaged patents,” one of which was directed to a “step-up diaper” and the other to a “stroller buddy.” Winfrey claimed that the PTO “improperly denied her two patent applications and wrongfully deemed the applications to be abandoned,” and that she was the true inventor of Huggies Pull-Ups diapers. Interpreting Winfrey’s requests for relief as claims under the FTCA and the APA, the district court dismissed the claims related to the step-up diaper patent application for failure to exhaust administrative remedies. The district court found that Winfrey never presented an administrative claim to the PTO as required by the FTCA and that she did not file a petition to revive the application after the PTO deemed it abandoned. The district court also dismissed Winfrey’s APA claim related to the stroller buddy patent application based on collateral estoppel because Winfrey had previously litigated that claim. Winfrey appealed.

Applying Eleventh Circuit law, the Federal Circuit affirmed the district court’s dismissal of all of Winfrey’s claims. Addressing the FTCA claim first, the Court noted that “nowhere in any of her extensive filings before this court do we find evidence that Ms. Winfrey filed the requisite administrative claim to bring a claim for money damages against the USPTO.” The Federal Circuit also affirmed the district court’s dismissal of claims related to the stroller buddy application based on collateral estoppel, finding that Winfrey had brought the claim unsuccessfully three times. Finally, with respect to the APA claim for the step-up diaper patent application, the Court affirmed the district court’s dismissal for failure to exhaust administrative remedies after finding that Winfrey failed to “present any evidence that she filed a petition with the USPTO to revive her application or challenge its abandonment determination.”

Rewind: Federal Circuit Grants En Banc Rehearing Over Royalty Damages

by | Oct 3, 2024 |

The en banc US Court of Appeals for the Federal Circuit issued a per curiam order vacating its previous panel decision upholding a district court’s denial of the defendant’s motion for a new trial on damages. In that decision, the Federal Circuit found that the plaintiff’s damages expert adequately demonstrated the economic comparability of prior license agreements to a hypothetical negotiation between the parties. Now, the Court has granted the defendant’s petition for rehearing en banc. EcoFactor, Inc. v. Google LLC, Case No. 23-1101 (Fed. Cir. Sept. 25, 2024) (per curiam) (Moore, C.J.; Lourie, Dyk, Prost, Reyna, Taranto, Chen, Hughes, Stoll, Stark, JJ.) Judge Prost dissented in part in the original panel decision.

EcoFactor sued Google over Nest thermostats allegedly infringing EcoFactor’s HVAC patent. The initial appeal revolved around the validity of the patent, the infringement verdict, and the damages awarded. Google argued that the patent was directed to an abstract idea and therefore was patent ineligible under 35 U.S.C. §101. Google also argued that the district court erred in its rulings on noninfringement and damages. The Federal Circuit majority upheld the district court’s decisions, finding genuine issues of material fact on patent validity, substantial evidence of infringement, and admissible expert testimony supporting the damages award. The Court dismissed Google’s challenge to the expert’s use of license agreements for calculating royalties, as the Court found the methodology reasonable. However, Judge Prost’s dissent in the original panel decision criticized the damages calculation, arguing that the expert’s methodology lacked rigor, particularly for failing to apportion the patented technology’s value from other licensed patents.

The en banc Federal Circuit will now reconsider the practice of using a patent owner’s prior license agreements to determine royalty rates, a method that can become complicated when the scope of licenses varies or when lump sums and royalties are not clearly apportioned.

The en banc order directed the parties to file new briefs limited to the issue of whether “the district court[] adhere[d] to Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), in its allowance of testimony from EcoFactor’s damages expert assigning a per-unit royalty rate to the three licenses in evidence in this case.”

When Can Same Claim Limitation Have Different Meanings? When It’s Functional, Of Course

by | Sep 26, 2024 |

Addressing for the first time whether a functional limitation must carry the same meaning in all claims, the US Court of Appeals for the Federal Circuit determined that it need not, vacating a district court decision to the contrary. Vascular Sol. LLC v. Medtronic, Inc., Case No. 2024-1398 (Fed. Cir. Sept. 16, 2024) (Moore, Prost, JJ.; Mazzant, Dist. J., by designation).

The seven patents asserted by Teleflex syin this case all come from a common application and are directed to a “coaxial guide catheter that is deliverable through standard guide catheters by utilizing a guidewire rail segment to permit delivery without blocking use of the guide catheter.” The asserted patents all share a common specification. However, the asserted claims differ in how they refer to the “side opening.” Some claims include the side opening as part of the “substantially rigid portion/segment” while other claims recite that the side opening is separate and distal to the “substantially rigid portion/segment.”

This case has a long procedural history involving an initial preliminary injunction motion and multiple inter partes reviews (IPRs). At the second preliminary injunction stage, Medtronic and the district court grouped the asserted limitations into two mutually exclusive groups:

  • Group One, which included the “substantially rigid portion/segment” claim limitation.
  • Group Two, which “required that the side opening not be in the substantially rigid portion” (emphasis supplied).

In denying Medtronic’s preliminary injunction motion, the district court questioned “how a skilled artisan could possibly be expected to understand the scope of a patent when the same device could simultaneously infringe two mutually exclusive claims within that patent.”

The district court then proceeded to claim construction. It rejected both parties’ initial constructions and appointed an independent expert – former US Patent & Trademark Office Director Andrei Iancu – to propose a construction. Teleflex argued that Iancu should adopt a split construction (i.e., one construction for the Group One limitations and another construction for the Group Two limitations). Medtronic argued that the claims were indefinite. Iancu rejected both proposed constructions but agreed with the district court on the mutual exclusivity of the two groups. The district court determined that all claims that included the “substantially rigid portion/segment” were indefinite, and since all the asserted claims included that term, the parties stipulated to final judgment. Teleflex appealed.

Teleflex argued that the district court erred in determining that the boundary of the substantially rigid portion must be the same for all claims. Medtronic argued that the claims were indefinite.

The Federal Circuit concluded that the district court erred when it determined that the Group One and Group Two limitations were mutually exclusive and indefinite. The Federal Circuit cautioned that affirming the district court’s conclusion would mean that claims in a patent cannot vary in how they claim the disclosed subject matter and that independent claims must be entirely consistent with other independent claims, neither of which is a restriction in how patentees may claim subject matter. The Federal Circuit explained that at the claim construction stage [...]

A New Vision: Collateral Estoppel Doesn’t Extend to Related Claims

by | Sep 19, 2024 |

The US Court of Appeals for the Federal Circuit reversed a district court order excluding expert validity testimony based on collateral estoppel stemming from an inter partes review (IPR) proceeding of a related patent, finding that an unpatentability decision in an IPR does not collaterally estop a patentee from making validity arguments about related claims in a district court litigation. ParkerVision, Inc. v. Qualcomm Inc., Case Nos. 22-1755; 24-2221 (Fed. Cir. Sept. 6, 2024) (Lourie, Mayer, Stark, JJ.)

This case has a long and complicated history. In 2011, ParkerVision sued Qualcomm for alleged infringement of eight patents related to wireless communications technology. In October 2013, a jury returned verdicts rejecting Qualcomm’s invalidity defense, finding 11 claims across four patents to be infringed by Qualcomm, and awarded $172 million in damages to ParkerVision.

In June 2014, the district court granted Qualcomm’s motion for a judgment as a matter of law on noninfringement, which the Federal Circuit affirmed in late 2015. Meanwhile, ParkerVision filed a second case against Qualcomm in May 2014 alleging infringement of 11 more patents. That case was stayed in favor of a Section 337 investigation that ParkerVision filed against Qualcomm at the International Trade Commission.

Qualcomm then filed 10 petitions for IPR, six of which targeted one of ParkerVision’s patents. While the challenged apparatus claims of that patent were found unpatentable during the IPR, the challenged method claims survived. The district court statutory stay (during the Commission proceeding) was lifted in December 2018. Prior to trial, the district court granted Qualcomm’s Daubert motions seeking to exclude ParkerVision’s expert’s testimony on invalidity due to collateral estoppel arising from the IPRs, and the expert’s testimony on infringement for being unreliable. The district court granted Qualcomm’s motion for summary judgment of noninfringement based on its finding that the asserted claims were materially similar to the claims from the first case. ParkerVision appealed.

In July 2024, after the briefing was completed and the Federal Circuit held oral argument, the Court dismissed the appeal for lack of appellate jurisdiction and returned it to the district court because Qualcomm’s invalidity counterclaims had not been adjudicated. The parties then filed a joint motion at the district court seeking entry of a final judgment, which was granted in August 2024. ParkerVision appealed again.

The Federal Circuit reinstated ParkerVision’s initial appeal and reversed the district court’s determination. On the summary judgment of noninfringement, the Court rejected the collateral estoppel finding because the district court failed to conduct claim construction to determine whether the scope of the claims was the same as in the first case. As for the district court’s exclusion of expert validity testimony due to the IPRs, the Federal Circuit concluded that because of the different legal standards for proving invalidity (preponderance versus clear and convincing), a finding underlying an unpatentability decision in an IPR does not collaterally estop a patentee from making validity arguments regarding related claims in district court litigation.

Finally, the Federal Circuit concluded that the district court had abused its discretion [...]

Stay Focused: New Point of View of Patent Eligibility

by | Sep 19, 2024 |

The US Court of Appeals for the Federal Circuit reversed and remanded a district court’s decision that the asserted claims were patent ineligible under 35 U.S.C. § 101, finding that the district court improperly characterized the claims at an “impermissibly high level of generality.” Contour IP Holding LLC v. GoPro, Inc., Case Nos. 22-1654; -1691 (Fed. Cir. Sept. 9, 2024) (Prost, Schall, Reyna, JJ.)

Contour owns two patents related to portable point-of-view (POV) video cameras. The patents disclose a hands-free POV action sports video camera configured for remote image acquisition control and viewing. The key embodiment describes “dual recording” where the camera generates video recordings “in two formats, high quality and low quality.” The lower quality file is streamed to a remote device for real-time adjustment of bandwidth limiting video parameters while the higher quality version of the recording is saved for later viewing.

In 2015, Contour sued GoPro, alleging that several GoPro products infringed the asserted patents. In 2021, Contour again sued GoPro, alleging that several newer products infringed the same patents. In 2021, after the district court granted partial summary judgment that GoPro’s accused products infringed the claims in the first lawsuit, GoPro filed a motion in the second lawsuit challenging the claims as patent ineligible under 35 U.S.C. § 101. GoPro relied heavily on the Federal Circuit’s 2021 decision in Yu v. Apple in its arguments for ineligibility. The district court initially denied the motion, but when GoPro raised the issue again at summary judgment, the district court agreed with GoPro and found the claims patent ineligible under § 101.

At step one of the Alice eligibility test the district court found that the claims were directed to the abstract idea of creating and transmitting video at two different resolutions and adjusting the video’s settings remotely. At Alice step two, the district court found that the claim recited only functional, result-oriented language without indicating that physical components behaved in any way other than their basic generic tasks. Contour appealed.

The Federal Circuit reversed, finding that when read as a whole, the claim was directed to a specific means that improved a relevant technology and required “specific, technological means – parallel data stream recording with the low-quality recording wirelessly transferred to a remote device – that in turn provide a technological improvement to the real time viewing capabilities of a POV camera’s recordings on a remote device.”

The Federal Circuit found that the district court’s decision was based on an “impermissibly high level of generality” that led to its incorrect conclusion that the claims were related to an abstract idea. The Court also disagreed with GoPro’s argument that Yu was dispositive in this case, explaining that in Yu, there was no dispute that the “idea and practice of using multiple pictures to enhance each other has been known by photographers for over a century.” The Court determined that Contour’s claim enabled a POV camera, with its dual recording capability, to operate differently than it otherwise [...]

Back to the Future: Expert Can Be Skilled Artisan Based on Later-Acquired Knowledge

by | Sep 12, 2024 |

The US Court of Appeals for the Federal Circuit clarified that a technical expert does not need to have been a person of ordinary skill in the art (POSITA) at the time of the invention. Instead, they may rely on later-acquired knowledge to offer testimony from the vantage point of a skilled artisan at the time of the invention. Osseo Imaging, LLC v. Planmeca USA Inc., Case No. 23-1627 (Fed. Cir. Sept. 4, 2024) (Dyk, Clevenger, Stoll, JJ.)

Osseo owns patents related to orthopedic imaging systems that use X-ray beam techniques to create tomographic and/or densitometric models of a scanned object. The alleged invention date of the patents was 1999. Osseo sued Planmeca for infringement of dental imaging systems that generate and display 3D models to a user.

At trial, the jury was instructed to determine the requisite level of ordinary skill and was told that a POSITA would have a bachelor’s degree in electrical or computer engineering, plus three to five years’ experience working in a diagnostic imaging environment that uses the techniques described in the asserted patents. During cross-examination, Planmeca sought to demonstrate that Osseo’s technical expert did not have the requisite experience in 1999, the alleged date of invention. The jury returned a verdict that Planmeca infringed the asserted patents.

After trial, Planmeca moved for judgment as a matter of law (JMOL), arguing that Osseo’s expert’s testimony should be disregarded because he was not a POSITA at the time of the patents’ alleged date of invention in 1999. The district court denied the motion as legally incorrect. Planmeca appealed.

Planmeca argued that the district court erred in denying JMOL because although Osseo’s expert became a POSITA eight to 10 years after the time of the invention, he was not so skilled at the time of the invention, and thus the verdict could not be supported by his testimony. The Federal Circuit reiterated that “[to] offer expert testimony from the perspective of a skilled artisan in a patent case – like for claim construction, validity, or infringement – a witness must at least have ordinary skill in the art.” The Court rejected Planmeca’s argument to add a timing requirement that the expert must have possessed the requisite ordinary skill in the art at the time of the invention. Instead, the expert must be qualified to offer testimony from the vantage point of a skilled artisan.

The Federal Circuit explained that it made little sense to add a timing requirement because an expert could acquire the necessary skill level later and develop an understanding of what a POSITA knew at the time of the invention. The Court noted that the fact that the expert was not a POSITA at the time of the invention may well be used during cross-examination to undermine the credibility of the expert but also noted that an expert could avoid such potential damage by explaining how they gained the perspective of a POSITA at the time of the invention.

Accordingly, the Federal Circuit affirmed [...]

Lower the Red Flags: Flawed Fee Award Flops

by | Sep 5, 2024 |

The US Court of Appeals for the Federal Circuit vacated and remanded a district court decision awarding attorneys’ fees, finding that the district court abused its discretion by failing to properly explain its basis for the fee award. Realtime Adaptive Streaming L.L.C. v. Sling TV, L.L.C., Case No. 23-1035 (Fed. Cir. Aug. 23, 2024) (Albright, Dist. J., sitting by designation; Moore, Lourie, JJ.)

Realtime Adaptive Streaming sued Sling and DISH for patent infringement related to digital data compression. The district court granted DISH’s motion for summary judgment of invalidity. While the invalidity finding was on appeal, the district court granted DISH’s motion for attorneys’ fees based on six so-called “red flags” that it found should have served as warning signs to Realtime that its case was fatally flawed.

The district court explained that the first red flag was two prior court decisions against Google and Netflix, which found similar claims of Realtime’s patent ineligible as abstract ideas under 35 U.S.C. § 101. Despite these decisions, Realtime pursued its claims. The second red flag came when the Federal Circuit ruled against Realtime in a related case. The third occurred when an inter partes review (IPR) proceeding invalidated key claims of Realtime’s patent. Following a nearly two-year stay, the district court identified the fourth and fifth red flags: a non-final office action from the US Patent & Trademark Office rejecting a key claim of the remaining patent, and a letter from DISH indicating its intention to seek attorneys’ fees if Realtime continued the case. The sixth red flag was an expert declaration from DISH that addressed invalidity of the claims at issue, and which was unfavorable to Realtime. Realtime appealed the district court’s attorneys’ fees award.

The Federal Circuit concluded that the district court erred by relying on the six so-called red flags without explaining the weight for each. Addressing the first flag, the Federal Circuit agreed with the district court’s reliance on the Google and Netflix decisions because they involved a patent with a virtually identical specification and essentially the same claims. The Court disagreed with the remaining red flags. The Court found that the second red flag related to a different technology and should not have put Realtime on notice that its patent claims were meritless. With respect to the third, fourth, and fifth flags, the Federal Circuit found that the district court did not adequately explain why these decisions supported exceptionality.

With regard to the sixth flag (the expert opinion), the Federal Circuit found that the district court’s analysis was insufficient. The Court explained that it is typical in a patent infringement case for the parties’ experts to disagree on invalidity issues. The Court found that Realtime and its expert developed critiques and counterarguments to DISH’s expert’s opinions, demonstrating that Realtime did not fail to give “serious consideration” to invalidity. While the district court may have found DISH’s expert more persuasive, that fact alone should not have put Realtime on notice that its claims lacked merit.

Accordingly, the Federal [...]

Later-Filed, Earlier-Expiring Patent Not an ODP Reference

by | Aug 29, 2024 |

Addressing invalidity due to obvious-type double patenting (ODP) based on later-filed-related patents, the US Court of Appeals for the Federal Circuit reversed a district court’s application of In re Cellect (Fed. Cir. 2023) and held that the later-filed, earlier-expiring continuation patents were not available as ODP references against the earlier-filed, later-expiring patent. Allergan USA, Inc. v. MSN Labs Private Ltd., Case No. 24-1061 (Fed. Cir. Aug. 13, 2024) (Lourie, Dyk, Reyna JJ.)

In 2015, the US Food and Drug Administration approved a new drug application for a drug sold by Allergan to treat the symptoms of irritable bowel syndrome. In 2019, Sun Pharma filed an abbreviated new drug application (ANDA) seeking to market a generic version of the drug. Allergan then sued Sun Pharma and MSN Labs for infringement of four patents related to the drug. One of the patents, which claims a compound of the drug, had been granted almost three years of patent term adjustment (PTA) and was followed by two more patents from continuation applications in the same patent family. The other three patents all claimed tablet forms of the drug. The claims of one of the patents recited that a glidant was optional while the claims of the other two patents did not require a glidant at all.

The US District Court for the District of Delaware held a three-day bench trial and concluded that the asserted claim of the compound patent was invalid under the ODP doctrine and that the claims of the three tablet patents were invalid for lack of written description. On the issue of ODP, the district court found Allergan’s “first-filed, first-issued” distinction “immaterial.” The district court stated that “[w]hen analyzing ODP, a court compares patent expiration dates, rather than filing or issuance dates.” Allergan appealed.

The Federal Circuit reversed on both issues. The Court held that the claims of the later-filed, earlier-expiring continuation patents were not available as ODP references against the first patent because the purpose of the ODP doctrine is to prevent patentees from obtaining a second patent to effectively extend the life of the first patent. The Federal Circuit explained that the district court misread Cellect as binding it to solely consider expiration dates in the ODP analysis. The Court explained that Cellect only controls to the extent that it requires a court to consider the later-filed patent’s expiration date (i.e., the expiration date after the addition of PTA) in its ODP analysis, not the expiration date that it would have shared with the reference patents in the absence of a PTA award. The panel majority emphasized that it does not follow that the later-filed patent must be invalidated by the earlier-filed reference patents simply because it expires later. The majority noted that “Cellect does not address, let alone resolve, any variation of the question presented here – namely, under what circumstances can a claim properly serve as an ODP reference – and therefore has little to say on the precise issue before us.”

The Federal Circuit also [...]
