In a development underscoring the intensifying battle over intellectual property in the semiconductor sector, Tachyum has initiated formal steps to defend its registered trademark for the term “TPU.” The company asserts that Google’s recent attempt to trademark “Google TPU” for its Tensor Processing Unit infringes upon rights Tachyum has held since 2020. This action highlights the growing significance of trademark clarity as competition in artificial intelligence hardware accelerates.
The dispute centers on the use of the three-letter acronym in the AI accelerator space. Tachyum, a designer of data center and AI processors, filed for trademark protection for “TPU” in September 2015, with registration granted by the United States Patent and Trademark Office (USPTO) in October 2020. The company uses TPU to denote its “Tachyum Processing Unit,” a licensable AI intellectual property core. In late November of this year, Google filed an application with the USPTO for “Google TPU,” relating to its well-known Tensor Processing Unit hardware.
The Legal Grounds of the Dispute
Tachyum’s strategy involves both a direct request to Google and a planned legal petition to the USPTO. The company has formally asked Google to cease using “TPU” as part of its product descriptor. Concurrently, it intends to challenge Google’s application during the trademark examination process, arguing that the registration should be refused due to a likelihood of confusion with its existing mark.
Understanding Trademark “Likelihood of Confusion”
At the heart of trademark law is the principle of preventing consumer confusion about the source of goods or services. The USPTO, and courts, use a multi-factor test to assess this. Key factors include the similarity of the marks, the relatedness of the goods or services, and the channels of trade in which they are sold.
Tachyum’s position hinges on the argument that both marks cover highly related goods—AI processor technology and intellectual property cores. The company licenses its TPU design for use in IoT and edge computing devices, providing developers with AI capabilities trained in data center environments. Google’s Tensor Processing Units are utilized both internally for AI workloads and externally via its cloud services, placing both companies’ goods in the overlapping spheres of AI computation and semiconductor technology.
The Challenge of “Coexistence” in Specialized Markets
A core tenet of trademark law allows identical marks to coexist only if they are used in sufficiently distinct markets where confusion is unlikely. For instance, a “Delta” faucet and “Delta” airlines operate in unrelated industries. Tachyum contends that this exception does not apply here. Both companies are operating in the competitive and interconnected field of AI hardware. The company states it is the sole registered owner of the TPU trademark within the AI space, and Google’s use of the term for a directly competing product category fails to represent the “distinct and different markets” required for peaceful coexistence.
Market Implications and Corporate Strategy
This legal maneuver is more than a procedural skirmish; it reflects the high stakes in the proprietary AI chip market. As companies seek to differentiate their hardware, brand identity becomes a critical business asset. A trademark is not merely a name but a symbol of origin and quality, accruing value alongside technological innovation.
The Value of a Licensable AI Core
Tachyum’s business model adds a layer of complexity to the dispute. By offering its TPU design as a licensable core, the company is not only a potential direct competitor but also a supplier of intellectual property to other developers. Market confusion over the “TPU” designation could, Tachyum argues, harm its licensing business prospects. If the term becomes generically associated with Google’s product, it could dilute Tachyum’s brand and create uncertainty for its licensees about the origin of the technology they are implementing.
A Statement of Principle
In a statement, Dr. Radoslav Danilak, founder and CEO of Tachyum, framed the action as a necessary defense of corporate assets. “We applied for and were granted trademark protection for TPU as part of our portfolio of internationally registered and trademarked IP,” said Danilak. “Google’s unlicensed use of TPU represents an infringement that creates confusion and harms our business prospects within the AI marketplace. Because of this, we are re-asserting our claim to the trademark rights of TPU as solely our corporate asset, and request that Google and others refrain from infringement to describe their similarly competitive products and services in the AI space.”
Danilak expressed confidence in the outcome, stating, “We fully expect a successful defense against Google’s redundant application of the term with the U.S. Trademark Office.”
Potential Outcomes and Industry Precedent
The path forward will likely be determined through USPTO proceedings. Google’s application will be examined by a trademark attorney who will consider Tachyum’s existing registration as a potential bar. Tachyum can formally file an opposition, triggering an adversarial proceeding before the Trademark Trial and Appeal Board (TTAB). Alternatively, the companies could reach a private coexistence agreement, though Tachyum’s current public stance suggests this is not its preferred initial outcome.
The technology industry has seen similar high-profile trademark disputes, often resolved through settlement or narrow licensing agreements that define specific fields of use. The outcome of this case could set a precedent for how trademark boundaries are drawn in the rapidly evolving and increasingly crowded AI hardware ecosystem, where product categories and market channels are constantly converging.
For now, Tachyum’s action serves as a pointed reminder that in the race for AI dominance, the battle lines are drawn not only in data centers and research labs but also in the meticulous and often contentious realm of intellectual property law.
