Case Study: Mintz Levin Secures Full Victory for Innovators in Lengthy Hatch-Waxman Battle

On October 10, 2017, the Southern District of New York (SDNY) entered judgment on a decision that closed the door on contentious federal district court Hatch-Waxman litigation that Mintz Levin handled on behalf of innovator pharmaceutical clients Kowa Pharmaceuticals and Nissan Chemical, handing our clients a complete victory on all asserted claims, and protecting their unique cholesterol-lowering medication, Livalo®.

Eight generic drug manufacturers filed Abbreviated New Drug Applications (ANDAs) with the US Food & Drug Administration (FDA) in 2014 and 2015, claiming that certain of our clients’ patents are invalid and/or would not be infringed by the drugs they planned to manufacture. To protect our clients’ interests, Mintz Levin’s team sued each of the generic manufacturers in a series of cases filed in the SDNY beginning in late 2014.

As part of their attack, defendants Mylan and Sawai petitioned for inter partes review (IPR) of one of the two patents before the Patent Trial and Appeal Board (PTAB). The Mintz Levin team successfully defeated those IPRs, resulting in the PTAB denying institution of all three petitions.

Throughout the process, the individual defendants attacked each patent with multiple theories of invalidity and/or non-infringement. The various defendants retained 18 defense experts in an attempt to support their attacks. As a result of Mintz Levin’s efforts, several defendants settled the litigation before trial, and another settled after trial. Three defendants — Amneal, Apotex and Lupin — remained in the litigation for trial, necessitating a 10-day trial in January 2017. The court issued separate decisions on each patent, with our clients prevailing in both decisions.

The first decision, handed down on April 11, 2017, upheld the validity of US Patent No. 5,856,336, which expires on December 25, 2020, and covers the active pharmaceutical ingredient in Livalo®, pitavastatin calcium, and its use for treating elevated cholesterol. The second decision, handed down on September 19, 2017, found that the proposed generic products of one of the remaining defendants would infringe (the other defendant had abandoned its non-infringement position), and upheld the validity of all asserted claims of US Patent No. 8,557,993, which expires on February 2, 2024, and which covers the polymorph of pitavastatin calcium contained in Livalo®.

The Kowa Pharmaceuticals and Nissan Chemical legal team was led by David Conlin and Kathleen Carr, and included Intellectual Property Members Adam Samansky, Thomas Wintner, John Bauer, and Kevin Ainsworth, Counsel Peter Cuomo, Jennifer Dereka, and Sharon O'Brien, Associates Joseph Rutkowski, Richard Maidman, and Megan Yung, and paralegal Vicki Francis.

Case Study: Victory at CAFC — PTAB Decision Reversed and Remanded

Straight Path IP Group came to us after another firm handled an inter partes review before the Patent Trial and Appeal Board in which the Board cancelled each of the challenged claims of Straight Path’s US Patent No. 6,108,704. Our team developed the appellate strategy, drafted the briefs, and argued the appeal before the Federal Circuit. The argument focused on the construction of two claim terms.  In an opinion issued on November 25, 2015, the Federal Circuit reversed and remanded the Board’s decision cancelling our client’s claims. See Straight Path IP Group, Inc. v. Sipnet EU S.R.O, No. 15-1212, (Fed. Cir. Nov. 25, 2015). It was the first time the Federal Circuit reversed a Board decision in its entirety, and only the second time it held that the Board erred in construing the claims of a patent.

International Trade Commission

  • Certain Graphics Systems, Components Thereof, and Consumer Products Containing the Same (337-TA-1044) Filed an ITC complaint on behalf of Advanced Micro Devices (AMD). The patented technology covers graphics processing technology employed by smart devices such as televisions and handsets. Respondents include LG, VIZIO, MediaTek, and Sigma Designs. The evidentiary hearing is scheduled for early December 2017.
  • Certain Memory Modules and Components Thereof, and Products Containing Same (337-TA-1023) Represent Complainant Netlist, Inc., a California memory module company, in the ITC asserting six patents against the Korean-based memory giant SK hynix. The technology claimed by the asserted patents is essential to the JEDEC DDR4 RDIMM and LRDIMM standards, which are implemented by the accused imported products. The respondents are asserting novel RAND defenses in the ITC, and in a co-pending case involving the same patents in the District Court for the Central District of California. The ITC evidentiary hearing is scheduled for early May 2017, while the trial in the CDCA is scheduled for July of 2018.
  • Certain Communications or Computing Devices and Components Thereof (337-TA-925) Represented owner of portfolio of communications and computing patents from former enterprise communications business unit of large multinational innovation company. An ITC investigation was instituted in August 2014 as to respondent entities Apple, Samsung Electronics, LG Electronics and HTC Corporation. Google participated as an intervenor. The investigation resolved prior to evidentiary hearing in June of 2015.
  • Certain Consumer Electronics with Display and Processing Capabilities(337-TA-884) Represented owners of the patent portfolio of the original Silicon Graphics, now known as Graphics Properties Holdings, as complainant in the ITC. Investigation was instituted in June 2013 and among the respondent entities were Panasonic, Toshiba, Vizio, and ZTE. Most respondents settled. After an evidentiary hearing held over several days in May 2014, on August 29, 2014 Mintz Levin successfully obtained a recommendation for a Limited Exclusion Order against the remaining respondent, which chose to settle while Commission review of the Administrative Law Judge’s Initial Determination was pending.
  • Certain Consumer Electronics and Display Devices and Products Containing Same (337-TA-836) – Represented owners of the patent portfolio of the former Silicon Graphics as complainant in the ITC, and as plaintiff in multiple parallel District of Delaware cases. Cases were filed between late 2011 and early 2012, and all were resolved by the end of January 2013. The technology at issue relates to LCD panels, central processor units, graphics processing units, and other microprocessor technology. Successfully licensed all respondents, including some of the largest and most recognized names in the converged device space — Apple, LG, Research in Motion, Samsung, and Sony.
  • Certain Portable Communication Devices (337-TA-827) – Represented complainant in the ITC and as plaintiff in multiple parallel District of Delaware cases. Successfully licensed all respondents, including some of the largest and most recognized names in the converged device space — Amazon, LG, Motorola, Pantech Wireless, Research in Motion, Sony, and more. Cases were filed in December 2011 and settled in May 2012.
  • Certain Electronic Imaging Devices (337-TA-726) – Represented complainant in this three-patent ITC case. Filed in June 2010 against converged device manufacturers and focused on digital camera technology found in cell phones, laptop computers, and personal digital assistants, the matter was fully settled in April 2011. The result was successful licensing programs with three out of four respondents, among which are recognized leaders in the electronics device manufacturing space — HTC, LG, Research in Motion, and more.
  • Certain LED Photographic Lighting Devices and Components Thereof (337-TA-804) — Represented a California-based complainant (plaintiff) and its UK parent, companies that make LED lighting systems for use in film and TV production, at the International Trade Commission. The ITC handed down its Final Initial Determination of infringement on September 7, 2012. On January 17, 2013, the ITC issued a General Exclusion Order (GEO) against respondents (defendants) based in both China and the United States. The result in this case is particularly notable because it is rare for the ITC to issue a GEO. It is much more common for complainants to seek and receive a Limited Exclusion Order from the court due to the rigorous criteria and careful balancing of interests that apply to requests for GEOs.
  • Certain Electronic Devices, including Handheld, Wireless Communications Devices (337-TA-667) – Represented complainant in three-patent ITC case and in parallel Federal District Court cases. Filed in December 2008, the cases were settled as to all respondents by May 2010 and resulted in successful licensing agreements with each, including some of the largest and most recognized names in the converged device space — HTC, Panasonic, Research in Motion, and more.
