That’s So Metal: Narrow Limitation Doesn’t Contradict Broader One

by | Mar 14, 2024 |

The US Court of Appeals for the Federal Circuit reversed a district court’s indefiniteness determination, finding that two claim limitations – one broad and one narrow – were not contradictory since it was possible to meet the requirements of both. Maxell, Ltd. v. Amperex Technology Limited, Case No. 23-1194 (Fed. Cir. Mar. 6, 2024) (Prost, Taranto, Chen, JJ.)

Maxell owns a patent directed to a rechargeable lithium-ion battery. Maxell filed suit against Amperex alleging infringement. Following claim construction proceedings, the district court found the claims to be indefinite based on two limitations in the independent claim that recited the variable M1. The relevant claim limitations read:

1- wherein M1 represents at least one transition metal element selected from Co, Ni and Mn, [. . .]

2- wherein the content of Co in the transition metal M1 of the formulae (1) and (2) is from 30% by mole to 100% by mole[.]

The district court found that these two limitations contradicted each other because limitation 1 recited Co (cobalt) as an optional transition metal selected from a Markush group for M1, whereas limitation 2 recited a minimum Co content of 30% in M1. The district court reasoned that the claims were indefinite because limitation 1 did not require the presence of cobalt, whereas limitation 2 did. In its claim construction order, the district court stated that simultaneous recitation that a claim element is both optional and required is a “contradiction on its face.” Maxell appealed.

The Federal Circuit found no contradiction between the two limitations, explaining that “[i]t is perfectly possible for a selected [M1] to satisfy both of these limitations.” The Court reasoned that in the context of Maxell’s patent, it was of no import that the two requirements (i.e., that M1 must comprise cobalt, nickel (Ni) or manganese (Mn), and that M1 must comprise at least 30% cobalt) were recited in separate clauses. It was enough that both limitations could be simultaneously satisfied. The Court further reasoned that the inclusion of two requirements in a claim did not create an otherwise nonexistent contradiction because the claim language must be read as a whole and not merely on a limitation-by-limitation basis. The Court also looked to the prosecution history to provide context for the ordering of the claim limitations at issue and explained that limitation 2 was added during prosecution to overcome a prior art reference that primarily used nickel as a transition metal.

The Federal Circuit explained that contrary to the district court’s characterization, the subject claim limitations did not grant options. Instead, they stated requirements that must be met to fall within the scope of the claimed invention. The Court noted that, rather than contradicting limitation 1, limitation 2 narrowed it. If limitation 2 had been recited in a dependent claim, there would be no contradiction, notwithstanding that proper construction of a dependent claim requires importation of all limitations from the claims from which it depends. The same conclusion applied when both limitations were [...]

Carolina Calling: Sources of Proof Favor Transfer

by | Feb 8, 2024 |

The US Court of Appeals for the Federal Circuit vacated a district court order denying transfer, finding that the sources of proof, compulsory process and localized interest factors all favored transfer. In re Honeywell Int’l Inc., Case No. 23-152 (Fed. Cir. Jan. 26, 2024) (Dyk, Bryson, Taranto, JJ.) (per curiam) (nonprecedential)

Lone Star SCM Systems filed a lawsuit against Honeywell in the Western District of Texas, Waco Division (West Texas) asserting infringement of four patents related to radio frequency identification technology. Honeywell moved to transfer the suit to the Western District of North Carolina (West Carolina), where Hand Held Products, a Honeywell subsidiary that designed, manufactured, imported and sold certain accused products, is headquartered. Honeywell argued that it had identified five potential Hand Held witnesses who would be subject to the transferee’s subpoena power and that relevant and material evidence would be more likely to exist in the transferee district.

The district court denied Honeywell’s motion. The district court analyzed public- and private-interest factors outlined in the Fifth Circuit’s 2008 In re Volkswagen of Am. decision and concluded that although Lone Star could have brought its suit in West Carolina, Honeywell had failed to demonstrate that West Carolina was clearly more convenient. The district court acknowledged that the bulk of the evidence was located in West Carolina but ultimately concluded that the convenience to potential party witnesses favored West Texas, pointing to several Lone Star witnesses who resided in the Northern District of Texas. The court found that the public-interest factors were neutral or similarly offsetting. The district court also found that West Carolina’s local interest favored transfer, but judicial efficiency did not because a transfer would have required relocating this suit away from two co-pending Lone Star infringement suits.

Honeywell petitioned the Federal Circuit for a writ of mandamus. The Federal Circuit determined that the district court’s denial of Honeywell’s transfer motion was patently erroneous. The Federal Circuit explained that the district court’s findings regarding potential party witness convenience and judicial efficiency were contrary to recent Fifth Circuit and Federal Circuit precedent. Regarding the potential party witnesses, the Federal Circuit cited the Fifth Circuit’s 2023 In re TikTok decision, explaining that it was improper to place witnesses residing outside of West Texas but still within the state of Texas on par with those residing in West Carolina. Regarding judicial efficiency, the Federal Circuit found that Lone Star’s position differed little from the circumstances that the Federal Circuit considered in its 2021 In re Samsung Elecs. decision, where the other suits involved different defendants with different hardware and software. Consistent with Samsung, the Federal Circuit concluded that Lone Star’s co-pending suits did not favor West Texas because the other cases were likely to involve significantly different discovery, evidence and issues. The Federal Circuit vacated the district court’s decision and ordered the district court to grant Honeywell’s transfer motion.

TikTok: Federal Circuit Follows Fifth Circuit, Transfers Case for Witness Convenience

by | Dec 21, 2023 |

In the first mandamus decision applying the US Court of Appeals for the Fifth Circuit’s new transfer motion guidelines under 28 U.S.C. 1404(a), the Federal Circuit followed suit and transferred a case for witness convenience. In re Samsung Elecs. Co., Ltd., Case No. 2023-146 (Fed. Cir. Dec. 14, 2023) (nonprecedential) (Prost, Hughes, Stoll, JJ.) (per curiam).

DoDots Licensing sued Samsung in the US District Court for the Western District of Texas (WDTX), alleging that Samsung phones and tablets infringed three DoDots patents. Samsung moved to transfer the case to the Northern District of California (NDCA). The applicable Fifth Circuit law allows for transfer only when the movant shows that the transferee forum is “clearly more convenient” than the transferor forum, which is determined by assessing a series of private and public interest factors. Echoing three of those factors, Samsung argued the following:

  • The teams that developed the allegedly infringing functionalities resided in NDCA and Korea.
  • Important third-party witnesses could be compelled to testify in NDCA but not in WDTX.
  • There was no meaningful connection between WDTX and the events giving rise to the suit.

Judge Albright denied the motion to transfer. He found that two factors weighed in favor of transfer: the ability to compel witness testimony and NDCA’s local interest in the case. However, Judge Albright also found that two factors weighed against transfer: WDTX was more convenient for certain witnesses, and DoDots’ co-pending and related lawsuits in WDTX meant that practical problems would arise if this case was transferred. The district court further determined that any remaining factors were neutral. Weighing all factors, the district court denied Samsung’s transfer motion, finding that Samsung had not shown that NDCA would be “clearly more convenient.”

Samsung filed a petition for writ of mandamus to the Federal Circuit, seeking to have the Court direct WDTX to transfer the case to NDCA. The sole question presented was whether, under Fifth Circuit law, the district court erred in refusing to transfer the case.

The Federal Circuit determined that the district court had clearly abused its discretion and that failing to transfer the case to NDCA had led to a “patently erroneous result.” The Federal Circuit found that the two factors that the district court determined weighed against transfer instead weighed in favor of transfer.

First, the Federal Circuit explained that the district court erred in finding that the “willing witness” factor weighed against transfer. Various Samsung entities had 10 relevant employees in NDCA and 20 in Korea. DoDots, in contrast, pointed to no potential technical or key witnesses in WDTX, although there were some Samsung marketing employees in Eastern Texas. The district court found that this weighed against transfer because any added travel from California to Texas for these technical witnesses was only a “slight” inconvenience. This argument echoed the argument that the Fifth Circuit rejected in its recent ruling in In re TikTok. In that case, the Fifth Circuit found on very similar facts that it was [...]

TikTok Makes It Out of West Texas to Sunny Northern California

by | Nov 16, 2023 |

The US Court of Appeals for the Fifth Circuit granted a writ of mandamus ordering the transfer of a case, finding that the district court’s denial of the motion to transfer “was so patently erroneous” that the extreme measure was appropriate. In re TikTok, Inc., Case No. 23-50575 (5th Cir. Oct. 31, 2023) (Smith, Southwick, Wilson, JJ.)

In the underlying case, Beijing Meishe Network Technology Co. sued TikTok in the US District Court for the Western District of Texas, alleging infringement, trade secret misappropriation and false advertising. All claims stemmed from the theory that a former Meishe employee disclosed copyrighted source code for video and audio editing software to TikTok, which TikTok then implemented into its app. Meishe and TikTok are Chinese companies, and both the alleged disclosure and TikTok’s alleged code implementation occurred in China, assisted by TikTok engineers in California. TikTok has no engineers in Texas but does maintain a business office there, although not within the Western District.

TikTok moved under 28 U.S.C. § 1404 to transfer the case to the Northern District of California. The district court took 11 months to rule on the motion, and in the meantime the case continued through discovery. After the district court denied the motion, TikTok petitioned the Fifth Circuit for a writ of mandamus.

The sole issue on mandamus was the propriety of the district court’s refusal to transfer venue. To succeed on a writ of mandamus, a petitioner must satisfy the reviewing court regarding the following questions:

  1. Are there other ways to obtain the desired relief?
  2. Is the reviewing court’s right to issue the writ “clear and indisputable”?
  3. Is the writ appropriate, given the circumstances?

The Fifth Circuit focused on the second question, its right to issue the writ. In the Fifth Circuit, the 2008 en banc In re Volkswagen case mandates an eight-factor test that a district court must consider in deciding a § 1404 transfer motion. No one factor is dispositive, and the Fifth Circuit has cautioned against tallying the yes/no results or denying transfer just because most factors are neutral. Unsurprisingly, in the 15 years since Volkswagen, district courts applying these factors have reached inconsistent results. Even the Fifth Circuit has reached “conflicting outcomes” when reviewing these cases. The Fifth Circuit therefore took the opportunity to address each factor.

The Fifth Circuit found that two factors weighed in favor of transfer:

  • The relative ease of access to sources of proof
  • The cost of attendance of willing witnesses

Regarding ease of access to proof, the Fifth Circuit clarified that factfinders analyze “relative ease of access, not absolute ease of access” to documents and other physical evidence. The district court had determined that this factor was neutral, given that most documentation was electronic. The Fifth Circuit disagreed, explaining that while the source code was electronically stored, it was protected by a high level of security clearance. Only certain TikTok employees based in California and China were able to access the code. Using the relative metric, [...]

Things May Be Bigger in Texas, but Not Necessarily More Convenient

by | Feb 16, 2023 |

The US Court of Appeals for the Federal Circuit granted a mandamus petition after analyzing the Fifth Circuit’s public and private interest factors for transfer motions and ordered the US District Court for the Western District of Texas to transfer a case to the petitioner’s venue. In re Google LLC, Case No. 23-101 (Fed. Cir. Feb. 1, 2023) (Lourie, Taranto, Stark, JJ.).

Jawbone Innovations, LLC, had an eventful 2021:

  • February: Incorporated in Texas
  • May: Obtained ownership of nine patents (all directed to technologies behind the eponymous product line that liquidated in July 2017)
  • August: Rented office space in Waco, Texas
  • September: Asserted the nine patents it just acquired against Google in the Western District of Texas–Waco Division.

Google moved to transfer the dispute to the US District Court for the Northern District of California. That district was where (1) the accused products (earbuds, smartphones, speakers, displays and software) were researched, designed and developed; (2) the asserted technology was developed, and the asserted patents were prosecuted; and (3) the witnesses and sources of proof were primarily located. In contrast, no witnesses or sources of proof were located in the Western District of Texas. Moreover, Jawbone Innovations had no personnel in Waco nor activities related to the accused technology in the whole of Texas.

Judge Albright nevertheless denied Google’s transfer motion, weighing the Fifth Circuit’s four public interest factors and four private interest factors and finding that the transferee venue failed to meet the Fifth Circuit’s “clearly more convenient” standard. With the district court finding half of the eight factors not favoring either the transferee or the transferor, its holding boiled down to a ruling that considerations of “court congestion” and “judicial economy” (found to favor the transferor) outweighed considerations of “unwilling witness compulsion” and the “cost of attendance for willing witnesses” (found to favor the transferee).

Google petitioned the Federal Circuit for a writ of mandamus. The Court, applying the Fifth Circuit’s eight factor test, identified clear error in the district court’s analysis of five of the factors.

First: Addressing the “cost of attendance for willing witnesses” factor, the Federal Circuit found error in the district court’s conclusion that this factor only slightly favored transfer. Rather, the Court explained that this factor “weigh[ed] heavily in favor of transfer” because the transferee venue was clearly more convenient for potential witnesses, especially Google employees with technical, marketing and financial knowledge of the accused products. The error was localized to how the district court considered a Google declaration identifying at least 11 potential employee witnesses (all of whom were located in the transferee venue) and Jawbone Innovations’ assertions that the declaration omitted three potentially relevant Texas-based employees. The Court noted that while this 11 to three imbalance alone was sufficient to settle this factor, the district court’s error went further, finding Google’s declaration unreliable and less worthy of consideration because of the alleged omissions. The Federal Circuit determined this was error on error because the district court improperly ignored that the depositions [...]

The Latest in SEP Licensing

Amol Parikh

The uncertainty surrounding standard essential patent (SEP) licensing persisted in 2022 and shows little sign of clearing in 2023. SEPs must be licensed to technology implementers on fair, reasonable and nondiscriminatory (FRAND) terms. Because there is no formal definition of FRAND terms, however, legal decisions involving FRAND have historically been determined by courts and non-governmental standard-setting organizations (SSOs). Disputes are frequent—especially between patent owners and technology implementers—and are becoming even more so as advanced wireless technologies such as 5G and WiFi 6 proliferate. Read more.

Trends in the Western District of Texas

Syed K. Fareed | Alexander Piala, Ph.D. | Christian Tatum

Over the past year, two developments infiltrated the Western District of Texas (WDTX) which may decrease the success of venue transfers and keep case volume steady in 2023. These developments could also give plaintiffs more control over where litigation takes place, including more control over having a case tried before Judge Alan Albright in the Waco Division of the WDTX.

Message to Judge Albright: Venue Motions Are First Order of Business

by | Nov 17, 2022 |

The US Court of Appeals for the Federal Circuit vacated a scheduling order from the US District Court for the Western District of Texas and directed the court to postpone fact discovery and other substantive proceedings until it considered a motion for transfer. In re: Apple Inc., Case No. 22-162 (Fed. Cir. Nov. 8, 2022) (Reyna, J.) The Federal Circuit ordered that Apple’s motion to transfer must proceed expeditiously as the first order of business, precluding fact discovery and other substantive matters. The Court has repeatedly scolded Judge Albright for his refusal to transfer patent cases out of the Western District of Texas.

Aire Technology sued Apple for patent infringement in October 2021. In April 2022, Apple moved to transfer the action to the US District Court for the Northern District of California, pursuant to 28 U.S.C. § 1404(a). During venue discovery, Apple submitted declarations by its employees, offered to make the declarants available for deposition, and stated non-opposition to a “reasonable continuance” of the transfer proceedings. Judge Albright granted Apple’s motion but sua sponte ordered the parties to complete fact discovery (which the court extended by 30 weeks) followed by another six weeks of rebriefing before he would rule on Apple’s request to transfer. Apple filed a petition for mandamus with the Federal Circuit seeking an order to vacate the district court’s scheduling order and promptly rule on the transfer motion, staying all proceedings on the merits until the transfer was resolved.

Apple argued that the district court abused its discretion in ordering the parties to complete 30 more weeks of fact discovery and six weeks of rebriefing the issue to decide on Apple’s transfer request. Apple noted that by the time the district court considered Apple’s motion, a full year would have elapsed since Apple initially sought the transfer, fact discovery would be completed, the parties’ infringement and invalidity contentions would be served, the asserted claims and prior art references would be narrowed, and the parties would have exchanged preliminary trial exhibits and witness lists.

The Federal Circuit agreed with Apple that the district court’s scheduling order went too far. The Court stated that “it is a clear abuse of discretion to require the parties to expend additional party and court resources litigating the substantive matters of the case while Apple’s motion to transfer unnecessarily lingers on the docket.” The Court noted that Aire consented to resolving Apple’s transfer motion at any time, provided that no stay interfered with discovery, claim construction proceedings or preparation of the case for trial.

The Federal Circuit disagreed with the district court’s view that delaying the decision until after full fact discovery and rebriefing could reduce “speculation” and “allow the parties to provide the court with the best evidence for ruling on a motion to transfer.” The Court stated that discovery on the transfer motion itself was sufficient to allow a decision of that motion, especially because the parties agreed that further venue discovery was unnecessary. The Federal Circuit ordered the district [...]

Golden State of Mind: Witness Convenience Isn’t Based Solely on Travel Distance

by | May 5, 2022 |

The US Court of Appeals for the Federal Circuit ordered a district court to transfer a patent infringement case from Texas to California because the district court had wrongly assessed facts relating to the convenience of witnesses when it originally denied a motion to transfer venue. In re: Apple Inc., Case No. 22-128 (Fed. Cir. Apr. 22, 2022) (Dyk, Reyna, Chen, JJ.) (non-precedential).

CPC Patent Technologies PTY Ltd. filed a lawsuit against Apple in the Western District of Texas, alleging that Apple’s mobile phones, tablets and computing products equipped with Touch ID, Face ID or Apple Card features infringed three of CPC’s patents relating to biometric security. Apple moved to transfer to the Northern District of California, arguing that its employees responsible for the design, development and engineering of the accused functionality resided either in California or outside of the United States, and that the employees most knowledgeable about the marketing, licensing and financial issues relating to the accused products resided in California. Apple explained that no employees with relevant information worked in Western Texas.

The district court denied Apple’s motion. After acknowledging that the action might have been brought in Northern California, the district court analyzed the private and public interest factors governing transfer determinations. The court determined that the factor concerning the convenience of willing witnesses slightly favored transfer. However, the court determined that the factor accounting for the availability of compulsory process weighed strongly against transfer. The district court also determined that court congestion and practical problems factors weighed against transfer based on its ability to quickly reach trial and the fact that CPC had another pending infringement suit in Western Texas. The district court recognized that Apple had identified seven relevant witnesses in California who would have to travel to Texas but found that inconvenience was counterbalanced by the presence of two Apple employees in Austin who CPC insisted had relevant information, and an Apple witness in Florida who would “find it about twice as inconvenient to travel to [Northern California] than to [Western Texas] because Texas sits halfway from Florida to California.” The district court also relied on its ability to compel the third-party Mac Pro manufacturer in Western Texas to attend trial. Finally, the Court noted that there was local interest in the dispute because Apple employs thousands of workers in Western Texas. Balancing these facts, the district court determined that Apple had failed to meet the burden of proving that Northern California was clearly more convenient that Western Texas, and thus denied the motion. Apple petitioned for mandamus review.

The Federal Circuit reversed, finding that Apple had shown clear entitlement to transfer to the Northern District of California. The Court found that the district court erroneously relied on two Apple employees in Austin whom CPC identified as potential witnesses and concluded that it was far from clear that either employee had relevant or material information. One employee had testified that he worked on authentication technology that was different from that accused by CPC, [...]

Judge Albright Issues Updated Standing Order for Patent Cases

by | Oct 28, 2021 |

On October 8, 2021, Judge Alan Albright of the US District Court for the Western District of Texas issued a new standing order governing proceedings for patent cases, which the Court designated as version 3.5 following previous updates in February and June 2021. The Western District of Texas manages more patent cases than any other district court in the United States.

The new order contains many refinements to Judge Albright’s procedures:

  • Recharacterizes the “default” schedule to be an “exemplary” schedule that the parties’ proposed schedule is expected to track in “most cases” and adds a date eight weeks prior to trial when the parties must email the court clerk to confirm the pretrial and trial dates
  • Requires parties with discovery disputes to summarize their respective positions to the court’s clerk when calling to schedule a conference with the court
  • Specifies the procedure for preparing the required email summary of discovery disputes and adds a 500-word limit per side
  • Notes that emails are the preferred method of contact with the court and that voicemail is not regularly checked and is not recommended
  • Removes a prior requirement to show good cause for extensions longer than 45 days to respond to the complaint
  • Extends the time to file a reply brief for a motion to transfer from seven days to 14 days
  • Deletes a previous provision by which substantive briefs could be submitted via audio file
  • Adds pages limits for Daubert motions (40 pages per side) and motions in limine (15 pages per side)
  • Requires that the paper copies of Markman briefs delivered to the Court be printed double-sided.
