In Allergan, Inc. v. Teva Pharmaceuticals USA, Inc. et al, Case No. 2:15-cv-1455-WCB (EDTX October 16, 2017 Order), a Federal District Court recently invalidated several patents covering Allergan’s dry-eye drug Restasis.  The ruling is notable because these are the same six patents Allegan just weeks ago transferred to the Saint Regis Mohawk Native American tribe in an effort to shield them from review at the Patent Trial and Appeal Board (“PTAB”).  This controversial transfer in an attempt to protect the patents from inter partes review at the PTAB via the tribe’s sovereign immunity received sharp criticism from generic drug manufactures and some in Congress.  Sovereign immunity, however, was not argued in District Court action.

The District Court dispute is a Hatch-Waxman Act case that relates to a condition known as “dry eye” and a pharmaceutical product known as “Restasis” that is intended to address that condition.  Restasis is an emulsion consisting of various components, including the active ingredient cyclosporin A, an immunosuppressant, which is dissolved in castor oil, a fatty acid glyceride.  Restasis, which is manufactured by plaintiff Allergan, Inc., is protected by six related patents, “the Restasis patents.”  Generic drug manufacturers Teva Pharmaceuticals USA, Inc.; Akorn, Inc.; Mylan, Inc.; and Mylan Pharmaceuticals, Inc., that wish to manufacture and sell bioequivalent drugs having the same components as Restasis challenged that the patents asserted by Allergan are invalid in defense to a patent infringement suit filed by Allergan.

Since this was a Hatch-Waxman Act case, the case was tried to judge and not a jury.  Thus, it was up to the court to make the factual determination as to the validity of the patents.  In determining the validity of the patents, the court found “that the prior art does not describe the Restasis formulation with sufficient specificity to satisfy the test for anticipation,” meaning no single reference invalidated any of the patents.  However, the court also found that “in view of all the evidence, including the prior art, the evidence of unexpected results, the evidence of objective considerations, and the motivation to combine the prior art references of Sall and the Ding I and Ding II patents, the Court concludes that the defendants have satisfied their burden of showing by clear and convincing evidence that the asserted claims of the Restasis patents would have been obvious.”  In other words, the court found the patents invalid on obviousness grounds, meaning multiple pieces of prior art in combination – and with a motivation to combine them- disclosed all limitations of the asserted patent claims.

Viewed from a broader perspective, the Court summarized from the evidence from the case as follows: “There is no doubt that Allergan has invented a useful and successful pharmaceutical product. It has been richly rewarded for that invention in large measure because it was able to get patent protection for the invention in 1995 when the Ding I patent issued. Allergan had 20 years of patent protection for its invention and ultimately for Restasis, the commercial embodiment of that invention, which was clearly covered by Ding I.

Although Allergan kept continuation applications alive for some years after Restasis was approved by the FDA, it ultimately conceded to the PTO in 2009 that the claims of the continuation applications that were directed to the Restasis formulation would have been obvious in light of the Ding I patent. However, in 2013, a few months before the expiration date of the Ding I patent, Allergan returned to the PTO, withdrew its concession of obviousness, and renewed its effort to obtain further patent protection for Restasis. Allergan’s theory in prosecuting the new applications was that the Restasis formulation, although falling within the scope of the Ding I patent, surprisingly produced exceptionally good results, so much so that the particular formulation for Restasis was entitled to patent protection even though that formulation fell within the scope of the ranges of values disclosed and claimed in Ding I. Allergan persuaded the examiner to issue the patent by way of a presentation that was more advocacy than science. The presentation suggested that the Restasis formulation resulted in efficacy levels up to eight times as great as would be expected based on studies of the formulations disclosed in the Ding I patent. In fact, a closer examination of the results of the clinical studies on which Allergan relied makes it clear that the presentation to the PTO substantially overstated the difference between the clinical results obtained with the Ding formulations and the clinical results obtained with the Restasis formulation. The actual clinical results, interpreted properly, show no significant difference in efficacy between the Restasis formulation and the 0.1% formulation that was Example 1D of the Ding I patent.

At trial, Allergan presented essentially the same theory—that the Restasis formulation produced results that were unexpected in light of the prior art—albeit without urging upon the Court the evidence that Allergan had presented to the PTO. In so doing, Allergan has had to deal with the problem that a considerable amount of highly pertinent prior art had accumulated by the 2003 priority date of the Restasis patents. Not only does the Ding I patent pose a problem for Allergan, but the papers by Sall and Stevenson revealed a great deal of information about the studies on which Allergan relies to make its unexpected results case.”

Thus, in light of this evidence, the Court concluded that Allergan is not entitled to renewed patent rights for Restasis in the form of a second wave of patent protection based on the extensive amount of pertinent prior art and the Court’s factual assessment of Allergan’s showing of unexpected results.  The Court therefore held that while Allergan has proved by a preponderance of the evidence that the defendants have infringed the asserted claims of the Restasis patents, the defendants have proved by clear and convincing evidence that the asserted claims of the Restasis patents are invalid for obviousness.

In sum, and while Allegan may appeal this ruling from the district court, the outcome of which is hard to predict, for now its Restasis patents were found invalid even after all the hassle Allegan went to protect them by assigning them to the Saint Regis Mohawk tribe.

Just Google it. Can you Google the score? Have you Googled the restaurant’s reviews? These are all common phrases in today’s internet-reliant society, and it’s entirely due to the creation of Google and its widespread success. By all measures, this should be a good thing for Google. Its company’s primary trademark, Google, has become such an integral part of society that it is now ingrained in our everyday vocabulary as a verb, and even further ingrained in our everyday usage. But for a company with valuable intellectual property rights in its Google trademark, its everyday usage in a general sense, meaning to perform an internet-based search, whether through Google or another search engine, could prove disadvantageous at some point in the future.

In fact, Google recently is currently dealing with an appeal involving these issues after a pair of individuals registered more than 700 domain names incorporating the word Google, including googlejxholdings.com, googleadam.com, and googlekellyclarkson.com. In response to these filings, Google filed a complaint with the National Arbitration Forum, claiming likelihood of consumer confusion and cybersquatting. The arbitration panel agreed with Google and transferred the domain names to Google. In ruling on the dispute, the panel found the domains confusingly similar to Google’s federally registered trademarks, and stated that the registrant had no legitimate interest in the domains and had registered them in bad faith.

Shortly after the arbitration panel issued its ruling, an individual who co-owned some of the domain names that the above-mentioned registrant was required to transfer to Google filed a lawsuit against Google in the United States District Court for the District of Arizona, attempting to cancel Google’s marks on the ground that they have become generic due to everyday verb usage. The registrant eventually joined the lawsuit as a plaintiff.

The plaintiffs moved the District Court for summary judgment, claiming that it was indisputable that the public used the word Google as a verb and “verb use constitutes generic use as a matter of law.” The District Court found in favor of Google, determining that the Google mark was not generic. As an example of another legitimately registered trademark often used as a verb to describe a category of activity, Judge Stephen M. McNamee cited the Photoshop trademark. Judge McNamee discussed how, much like Google, people often use Photoshop to refer to something aside from Adobe’s trademarked product. Judge McNamee further remarked that “It cannot be understated that a mark is not rendered generic merely because the mark serves a synecdochian ‘dual function’ of identifying the genus of services to which the species belongs.”

Still unsatisfied, the plaintiffs petitioned the 9th Circuit for review. In an opinion written by Circuit Judge Richard Tallman, the 9th Circuit reiterated Judge McNamee’s findings and once again acknowledged that the mere use of a word as a verb is insufficient to show genericide. But apparently the opinions of Judge McNamee and Judge Tallman are still not enough for these plaintiffs. They have now petitioned the Supreme Court for review.

The petition for review calls the 9th Circuit’s decision “dangerous” for holding that the use of a trademark as a verb is irrelevant to the determination of whether it has become generic. It also states that the decision is in conflict with the opinions of various experts who have stated that trademarks are proper adjectives, which should not be used as verbs. According to the petition, “[u]nchecked indiscriminate verb usage of trademarks could, and will, lead to a reality where the public can no longer recall that the verb derives from a trademark, while simultaneously allowing the trademark to exist on the principal register in perpetuity[.]” Finally, the petition states that public appropriation of Photoshop, Xerox, and other marks is something to be encouraged, as it is an example of how language is a dynamic, living being, meeting the needs of speakers.

It would be interesting to see how the Supreme Court would rule on this matter, but given that the Supreme Court only grants review to a select number of cases, I suspect we will not find out. This is especially true given that neither the 9th Circuit nor the District Court stated that verb use is irrelevant to the analysis, as it is represented in the petition, but simply that verb use alone is insufficient to demonstrate genericide. However, stranger things have happened.

Until the U.S. Supreme Court’s May 22, 2017 ruling in TC Heartland v. Kraft Foods, the Court of Appeals for the Federal Circuit and the United States district courts had interpreted the patent venue statute, 28 U.S.C. §1400(b), to allow plaintiffs to bring a patent infringement case against a domestic corporation in any district court where there is personal jurisdiction over that corporate defendant.  The Supreme Court’s TC Heartland ruling, however, clarified that personal jurisdiction alone does not convey venue for patent cases under the patent venue statute.  But that clarification led to confusion as to how to interpret the venue statute itself.  The Federal Circuit just addressed that confusion in In re Cray Inc. 

Specifically, the patent venue statute provides that “[a]ny civil action for patent infringement may be brought in either 1) “the judicial district where the defendant resides” or 2) “where the defendant has committed acts of infringement and has a regular and established place of business.”  Prior to TC Heartland, courts had found that a domestic corporation resides in any judicial district where the corporation is subject to personal jurisdiction, and thus venue was proper in those districts.  In TC Heartland, the Supreme Court limited venue under the first prong explaining that a corporation only resides in its state of incorporation.  For plaintiffs wishing to sue corporations in judicial districts outside the defendant’s state of incorporation, the TC Heartland ruling shifted the focus to the second prong of the patent venue statute.  The second prong states that a domestic corporation can be sued for patent infringement “where the defendant has committed acts of infringement and has a regular and established place of business.”

Following TC Heartland, defendants filed a flurry of motions to dismiss for lack of venue or, in the alternative, to transfer cases.  Corporations argued they had been improperly sued in venues where they had no “regular and established place of business.”  But what is a “regular and established place of business”?  Prior to the TC Heartland ruling, venue was typically shown under the first prong based on where a corporation resides, so the courts had not really dealt with the requirements for a “regular and established place of business” under the second prong of the venue statute.  Now courts were forced to address this issue and different courts were coming to different conclusions, which led the Federal Circuit to address this issue in response to Cray’s petition for a writ of mandamus.

Cray’s petition arose from Judge Gilstrap’s venue ruling in Raytheon Co. v. Cray, Inc. (“Transfer Order”).  More specifically, Raytheon filed a patent infringement action against Cray in the Eastern District of Texas.  Cray is a Washington corporation.  Cray did not rent or own property in the Eastern District of Texas but allowed two employees to work remotely from their homes in that district.  One of those employees was a “sales executive” with sales in excess of $345 million over approximately seven years.  That employee received reimbursement for cell phone charges, internet fees, and mileage related to his work for Cray.  The employee, however, did not store products or product literature in his home.  Further, he was never paid for use of his home as a business office.  Cray moved to transfer the case for lack of venue arguing that it did not reside in the district and did not maintain a regular and established place of business in the district.

In his Transfer Order, Judge Gilstrap not only found venue proper in the Eastern District of Texas but also went on “‘[f]or the benefit of’ other litigants and counsel to set out four factors for inquiries into what constitutes a regular and established place[] of business ‘in the modern era,’ including physical presence, defendant’s representations, benefits received, and targeted interactions with the district.”

The Federal Circuit reversed stating that “[a]lthough the law was unclear and the error understandable, the district court abused its discretion by applying an incorrect legal standard, which we now clarify in this opinion.”  The Federal Circuit explained that its “analysis of the case law and statute reveal three general requirements” for whether a corporation has a “regular and established place of business” in a judicial district.  These requirements include:  “(1) there must be a physical place in the district; (2) it must be a regular and established place of business; and (3) it must be the place of the defendant.

The Federal Circuit further explained that while the “‘place’ need not be a ‘fixed physical presence in the sense of a formal office or store,” “there must still be a physical, geographical location in the district from which the business of the defendant is carried out.”  A test that encompasses virtual spaces or electronic communications would improperly expand the venue statute.  Further, “the mere fact that a defendant has advertised that it has a place of business or has even set up an office is not sufficient; the defendant must actually engage in business from that location.”  In addition, for a business to be “regular and established,” the activity cannot be sporadic or transient in nature.  Further, “[t]he defendant must establish or ratify the place of business.  It is not enough that the employee does so on his or her own.”  Therefore, an employee that merely works from home does not necessarily create venue in the district.

It is now clear that personal jurisdiction and venue or two separate requirements for patent infringement cases.  Further, in many instances, plaintiffs will have significantly fewer options for the districts where they can bring patent infringement cases against domestic corporations under the patent venue statute.

 

Brand litigation can be extreme in the consumer products space and even more so for alcoholic beverages (legal cannabis brand owners take note and start stockpiling your war chest).  It’s not uncommon for litigation to arise whenever an alcoholic beverage brand owner believes that another alcoholic beverage brand infringes.  Such was the case for Sazerac Company, the maker of the high quality bourbon BUFFALO TRACE.  Sazerac became concerned that Fetzer Vineyards’ use of a buffalo design and the word “bourbon” on a wine label would cause consumer confusion.

   

In its complaint Sazerac alleged that:

Fetzer Buffalo Design and Trade Dress are confusingly similar to Sazerac’s BUFFALO Marks and BUFFALO TRACE Trade Dress.  Each of the 1000 Stories’ bottles prominently features the Fetzer Buffalo Design, which is a sketched rendering of a standing, left-facing, fur-covered buffalo, similar to the Buffalo Logo and Buffalo Outline displayed on Sazerac’s BUFFALO TRACE product packaging.  In addition to this confusingly similar representation of a buffalo, the bottle text prominently reads “AGED IN BOURBON BARRELS,” and the website marketing specifically references the wine’s aging process in bourbon barrels from “famed distilleries,” tacitly suggesting an association with such distilleries.  It is readily apparent that Defendant chose the illustration and particular artistic stylization of a Buffalo to create a false association with Sazerac’s BUFFALO TRACE brand.

Sazerac alleged in its complaint that theirs and Fetzer’s wine would be sold in the same commercial channels – “Sazerac’s BUFFALO TRACE product and Defendant’s 1000 Stories product are competing, or will compete, in identical retail outlets – for example, wine and liquor stores, bars, restaurants, and online retail sites” – and be marketed to the same group of consumers – “Defendant, like Sazerac, markets its 1000 Stories product to adult consumers and adult purchasers of alcoholic beverage products.”

Sazerac’s claim of likelihood of confusion falls in line with the trend of the Trademark Trial and Appeals Board to find beer, wine and spirits related goods for the purposes of determining likelihood of confusion.  The TTAB has found support for this position based on third-party evidence showing manufacturers produce various types of alcoholic beverages under a single mark.  In re Uinta Brewing Company, the TTAB found persuasive eleven websites that showed breweries also selling wine; In re Sugarlands Distilling Company, LLC, the TTAB cited five examples of wineries also engaged in distillation and the sale of spirits; In re Sonoma Estate Vintners, LLC, the TTAB found persuasive fifteen registrations showing that various entities registered a single mark for wine and beer.  The TTAB also finds that alcoholic beverages are sold in the same channels of trade, such as liquor stores and restaurants, which means  that consumers will encounter multiple types of alcoholic beverages in the same stores.  The TTAB also commonly finds that consumers purchase alcohol without exercising great care.

Most often cases such as these settle.  This case, however, went all the way to a bench trial after which the judge rendered an opinion which began with the statement “In the final analysis, this case was not close.”

First the court found that Sazerac failed to establish a claim of trademark infringement.  The court noted that Sazerac relied on the “colorable imitation” theory of trademark infringement, but failed to present any evidence that Sazerac’s buffalo logo trademark creates the same commercial impression as Fetzer’s buffalo.  The court noted that Sazerac consistently argued that it was the combination of Fetzer’s buffalo and its reference to “bourbon” in “BOURBON BARREL AGED” that confused consumers as to the source of Fetzer’s wine.  This, the court noted, is a trade dress claim.

Trade dress involves the total image of a product and may include features such as size, shape, color, color combinations, texture, or graphics.  Trade dress protection is broader in scope than trademark protection, both because it protects aspects of packaging and product design that cannot be registered for trademark protection and because evaluation of trade dress infringement claims requires the court to focus on the plaintiff’s entire selling image, rather than the narrower single facet of trademark.  To establish a trade dress infringement claim, a plaintiff
must prove: “(1) the trade dress is inherently distinctive or has acquired distinctiveness through
secondary meaning; (2) there is a likelihood that the public will be confused by the infringing
use; and (3) the trade dress is nonfunctional.”

In reviewing these elements, the court found that Sazerac failed to establish that its trade dress is distinctive or that it had acquired secondary meaning.  Distinctive trade dress occurs when the trade dress is of such an unusual design that it automatically distinguishes itself from its competitors.  In finding Sazerac’s trade dress not distinctive, it found persuasive the “extensive evidence of other alcoholic beverages…that include buffalo image[s]” and that the Buffalo Trace brand has low brand recognition since it comprises only .5% of the whisky market.

Further, the court said that Sazerac failed to present evidence of direct consumer testimony or survey findings showing that its claimed trade dress had acquired secondary meaning.  While Sazerac relied on evidence showing significant marketing expenditures, the court said that Sazerac failed to demonstrate how its marketing efforts effectively created secondary meaning.

The court made quick work of analyzing the similarity of the trade dress.   While both use realistic sketched renderings of a buffalo and use the term “bourbon”, the court found that all of the other elements are different.  In the end, the court found that Sazerac failed to present any evidence that the overall appearance of Fetzer’s wine is so similar to its Buffalo Trace trade dress that it is likely to confuse consumers.

In addressing the trade channels, the court acknowledged that both bourbon and wine participate in the same general alcoholic beverage industry and are advertised and sold in overlapping channels.  However, the court found that wine and bourbon are “very distinct products” with “different alcohol contents and social uses” and they “occupy different sections of the stores where they are offered for sale.”  The court found that “the proximity or relatedness of these alcoholic beverage products may weigh slightly in Sazerac’s favor, but not significantly so.”

Lastly, the court noted that purchasers of premium alcoholic beverages tend to exercise a high degree of sophistication and care when making their purchasing decisions and cited to the 2005 Second Circuit case of Star Indus., Inc. v. Bacardi & Co. for the authority that “Unhurried consumers in the relaxed environment of the liquor store, making decisions about $12 to $24 purchases, may be expected to exhibit sufficient sophistication to distinguish between Star’s and Bacardi’s products, which are differently labeled.”  Given a $14 price point for Fetzer’s wine, the court found that “[p]urchasers of a premium red zinfandel, therefore, are expected to exercise a high degree of care and are not likely to make mistakes as to a product’s sponsorship or affiliation.

While the court’s finding of no infringement was “not close”, it will be interesting to see what effect, if any, the court’s reasoning may have on the USPTO or TTAB in refusals to register a brand for wine based on likelihood of confusion with a brand for spirits (or visa versa).  The court’s opinion guts two significant factors upon which the USPTO and TTAB have based refusals to register.

In In re Stepan Co., 2017 U.S. App. LEXIS 16246, decided August 25, 2017 the Federal Circuit Court of Appeals made it very clear that during patent prosecution, the burden of proving patent ability lies with the PTO examiner. 

The patent applicant was Stepan Co., who filed a patent application for formulas of an herbicide.  The herbicide was a composition of a glyphosate salt and a surfactant system.  The claims required the formula to have a cloud point above 70ºC or no cloud point.  The cloud point is the temperature at which a liquid turns cloudy because its components are separating.  The herbicide formulas had to have a cloud point above 70ºC to prevent the surfactants from separating.

The PTO examiner rejected all of Stephan Co.’s claims on the grounds that they were obvious over the prior art.  The prior art did not have the same cloud point or the same components, but the examiner stated that the claims were obvious because a person skilled in the art would have achieved the claimed parameters by “routine optimization” of the formula.  The examiner also found that, based on general statements in the prior art references, the skilled artisan would have been motivated to create the claimed formula.

On appeal to the Patent Trial and Appeal Board, the PTAB affirmed the examiner’s conclusion that all of Stepan Co.’s claims were obvious.  The PTAB held that Stepan Co. had not rebutted the prima facie case of obviousness established by the examiner.  The PTAB said that Stepan Co. had not produced evidence that a skilled artisan would not have achieved a cloud point above 70ºC by routine optimization.  The PTAB did not consider Stepan Co.’s evidence that the prior art references disclosed compositions that had a cloud point of 60ºC (and therefore taught away from compositions that could be used at a higher temperature).  In addition, the PTAB found that Stepan Co. did not show that a cloud point above 70ºC was critical to the compositions or that it yielded unexpected results.

On appeal, the Federal Circuit vacated the PTAB’s decision.  The court explained that in order to make a finding of obviousness, the PTO must show “that a skilled artisan would have been motivated to combine the teachings of the prior art … and that the skilled artisan would have had a reasonable expectation of success.”  These are questions of fact reviewed by the appellate court for substantial evidence.

The Federal Circuit found that the PTAB had made several errors: it did not articulate its reasoning for its finding of obviousness; it rejected Stephan Co.’s evidence of non-obviousness; and it shifted the burden of proof of patentability to the applicant.

First, the Federal Circuit held that PTAB had to explain why “routine optimization” would have produced the claimed composition.  The PTAB’s conclusion was not sufficient.  According to the court:

“Stating that a person of ordinary skill in the art would have arrived at the claimed invention through routine optimization falls short of the standard.  Missing from the Board’s analysis is an explanation as to why it would have been routine optimization to arrive at the claimed invention.  . . . [T]he Board must provide some rational underpinning  explaining why a person of ordinary person in the art would have arrived at the claimed invention through routine optimization.”

Second, the PTAB did not set forth why the skilled artisan would have had a reasonable expectation of success in modifying the prior art.  The PTO has to show that a skilled artisan “must be motivated to do more than merely vary to all parameters or try each of numerous possible choices until one possibly arrived at a successful result.”

Third, the PTAB ignored Stepan Co.’s evidence that the prior art disclosed failures that were relevant.  These failures showed why a skilled artisan would not have had a reasonable expectation of success in modifying the prior art references.

Fourth, the PTAB shifted the burden of patentability to Stepan Co.  “The PTO bears the burden of establishing a prima facie case of obviousness…. ‘Only if this burden is met does the burden of coming forward with rebuttal argument or evidence shift to the applicant.’”  The Board improperly required Stepan Co. to demonstrate why the cloud point was a critical element of the claimed composition.

Because of the PTAB’s errors, the Federal Circuit vacated the decision and remanded the case for further proceedings.
