“Ultimately, the Federal Circuit faces a momentous choice: Affirm the PTAB’s standing as an obvious worldwide outlier—thereby denying the Nobel Prize winners—or reverse the PTAB, which will be equally difficult.”
On Tuesday, Might 7, the U.S. Court docket of Appeals for the Federal Circuit will hear argument in a long-awaited attraction addressing the inventorship of the Nobel Prize-winning CRISPR know-how. The case is the newest in a seamless authorized battle between two teams of innovators, every asserting patent rights to key facets of the groundbreaking know-how.
The information on attraction are quite a few, and the problems nuanced, protecting questions of conception, discount to observe, and written description (in addition to cross-appeal points). This text’s goal is to not reiterate either side’s numerous authorized positions, however to discover a narrower difficulty intertwined with the worldwide CRISPR patent disputes: concerns of patent harmonization and the thus-far inconsistent patent outcomes.
The CRISPR Wars
“CRISPR” is an acronym for “Clustered Repeatedly Interspaced Brief Palindromic Repeats.” As many readers know, CRISPR know-how permits precision gene enhancing. The technology’s potential benefits are monumental, a few of that are already being realized with the FDA’s approval of CRISPR-based therapies late last year.
Competing patents and purposes have been awarded and filed in the US and throughout the globe. On one facet are Jennifer Doudna and Emmanuelle Charpentier (the 2 Nobel Prize winners), together with their analysis establishments, collectively often called the CVC appellants. On the opposite facet are Feng Zhang and his colleagues on the Broad institute, MIT, and Harvard, collectively often called the Broad cross-appellants.
A primary side of the pending dispute is who first invented (to a passable diploma, below patent legislation) a CRISPR system that might work in eukaryotic cells. Recall from highschool biology that prokaryotic cells shouldn’t have a nucleus, however eukaryotic cells do. The previous are usually earlier on the evolutionary scale and thus much less advanced, however the two varieties of cells nonetheless have many frequent methods and options.
CVC filed its patent software describing the CRISPR-Cas9 advanced and claiming its use in eukaryotic cells sooner than Broad, however Broad filed a patent software with experimental ends in eukaryotes sooner than CVC. CVC additionally asserted an earlier invention date (by conception and discount to observe). The case to be argued this week on the Federal Circuit issues the Patent Trial and Attraction Board’s (PTAB’s) interference choice, which awarded precedence of the invention’s use in eukaryotic cells to Broad. (Notice that that is not the first CRISPR dispute to achieve the Federal Circuit).
CVC’s CRISPR patents are being challenged in a number of patent tribunals, in the US, Europe, Japan, and China. Intriguingly, the PTAB is the one patent workplace to this point to rule in opposition to CVC’s patents for the eukaryotic CRISPR system. As described under, the challenges within the different three fora have usually been in CVC’s favor.
The disparate outcomes could supply the Federal Circuit a motive to account for harmonization concerns when it hears oral argument. Whereas harmonization just isn’t front-and-center of the attraction—and was not expressly briefed by the events—the Court docket should wish to ask why the PTAB was the obvious outlier as the one adjudicator to this point to rule in opposition to the Nobel Prize winners.
Harmonization Throughout Nations Can Enhance Biotechnology Innovation
Harmonization of patent legal guidelines advances objectives of incentivizing and enabling innovation, particularly within the areas of doubtless lifesaving, life-altering applied sciences. As an illustration, in August 2011, then-Director Kappos outlined the significance of patent legislation harmonization:
“Harmonization—the alignment of legal guidelines and procedures amongst mental property (IP) methods to make sure consistency and readability of rights for the world’s innovators—is a prerequisite to maximizing the event and dissemination of innovation and thereby bettering high quality of life for all of the world’s folks.”
David J. Kappos, The Time Is Now, Landslide 16-17 (July/Aug. 2011).
The America Invents Act (AIA) was one other effort to harmonize U.S. patent legislation with the legislation of different nations. Because the USPTO stated: “The [AIA] paves the best way for larger patent harmonization-the alignment of legal guidelines and procedures amongst mental property methods to make sure consistency and readability of rights for the world’s innovators.” U.S. Patent and Trademark Workplace, Harmonization: The Time is Now (final modified Oct. 31, 2019).
Earlier than the AIA, the “IP5” was advancing harmonization efforts. Based in 2007, the IP5 consists of the European Patent Workplace (EPO), U.S. Patent and Trademark Workplace (USPTO), the Japan Patent Workplace (JPO), the Korean Mental Property Workplace (KIPO), and the Nationwide Mental Property Administration of the Folks’s Republic of China (CNIPA), the five largest patent offices on the planet.
Even earlier, the biotechnology business was recognized as an space the place world harmonization efforts are necessary concerns. See, e.g., Nationwide Analysis Council, Global Dimensions of Intellectual Property Rights in Science and Technology 319 (1993).
The Non-Harmonized CRISPR Outcomes
With a broad consensus for harmonizing patent legislation to higher allow innovation, an intriguing side of the continued CRISPR litigation is how the PTAB reached a special choice in comparison with the opposite patent places of work. Whereas there needs to be no expectation of identicality among the many disputes, one should surprise how the PTAB reached a choice at odds with the selections within the EPO, Japan, and China.
Take the EPO oppositions. There, the Opposition Division made a number of conclusions recognizing that excellent predictability just isn’t required when describing and claiming pioneering and groundbreaking know-how. In a single choice, the Opposition Division expressly concluded that CVC’s patent “permits Cas9-mediated and sgRNA-directed cleavage of DNA in cells together with eukaryotic cells.” In doing so, the Opposition Division famous that “[e]nablement is met when it’s believable that cleavage will be achieved in any respect i.e. regardless of its effectivity” and that “[e]fficiency of the system nevertheless is to not be confounded with the plausibility of it being realisable.” See, e.g., ’811 Opp. at 25, ¶ 36.1.2.20.
In one other choice, the Opposition Division was additionally persuaded by “[t]he incontrovertible fact that shortly after the date of submitting of [CVC’s patent application],” “completely different scientific teams have been in a position to implement the CRISPR/Cas system in eukaryotic cells.” That truth was, in response to the Opposition Division, “additional proof that there was no undue burden concerned.”
In distinction, the PTAB seems to have thought of the identical or comparable proof however concluded that the CVC group had not carried out sufficient to ascertain precedence to its earliest-filed patent software. As one instance, the PTAB discovered CVC’s patent software “didn’t disclose particular directions or circumstances essential for CRISPR-Cas9 exercise in a eukaryotic cell, or point out that no particular directions or circumstances have been essential.”
Past the EPO choice, CVC has prevailed in disputes in China and Japan. As reported in April of this year, “China’s patent and trademark workplace has upheld a key patent throughout the portfolio of CRISPR/Cas9 mental property belonging to [CVC].” China’s decision follows the December 2023 choice by the Japan Patent Workplace, which upheld a CVC-filed patent additionally with eukaryotic CRISPR claims.
How Will the Federal Circuit Deal with Harmonization Issues?
There are, after all, many extra related information than the few highlighted right here. Moreover, the selections in Europe, China, and Japan are topic to attraction and thus not ultimate. These choices nonetheless underscore that the PTAB, to this point, is the outlier in the way it views the CRISPR inventorship dispute—which units the stage for some intriguing questions on attraction.
First, why is the PTAB standing alone? It’s attainable that variations in proof are to elucidate, though that appears unlikely to be a dispositive foundation. Either side have among the greatest patent attorneys and litigators concerned within the numerous disputes, and the important thing proof seems very comparable.
Maybe the differential outcomes movement from the more and more stringent written-description and enablement necessities below 35 U.S.C. § 112. It’s no secret that current choices of the Supreme Court docket (Amgen v. Sanofi) and the Federal Circuit (e.g., Juno v. Kite) have intensified § 112 requirements. Maybe the inconsistent CRISPR outcomes are manifestations of an growing chasm between U.S. enablement and written-description legislation and the analogous necessities below European, Chinese language, and Japanese patent legislation.
One other query is how a lot of a job, if any, ought to harmonization and world innovation-incentivizing issues play within the Federal Circuit’s decision-making. On the finish, the patent system’s objective is to allow and incentivize innovation, and the court docket’s choices ought to at all times apply that gloss to its decision-making. To make sure, world harmonization can’t be the controlling issue, however a discerning eye should study the PTAB’s choice in mild of the opposite main patent places of work’ completely different conclusions.
Ultimately, the Federal Circuit faces a momentous choice: Affirm the PTAB’s standing as an obvious worldwide outlier—thereby denying the Nobel Prize winners—or reverse the PTAB, which will be equally difficult. The authors right here take no stance on the “right” end result. We write primarily to focus on how this attraction has even broader implications past the importance of the groundbreaking know-how.
