TSMC has responded to GlobalFoundries accusations of patents infringements. The world’s largest foundry said that it would defend itself in courts and that it considered allegations as baseless. The contract maker of semiconductors said that throughout its history it was granted 37,000 patents and naturally considers itself one of the leaders in the industry.

On Monday GlobalFoundries said that TSMC, a number of its customers, as well as makers of various products infringed 16 of its patents covering various aspects of chip manufacturing. In particular, GlobalFoundries claims that TSMC’s 7 nm, 10 nm, 12 nm, 16 nm, and 28 nm nodes illegally use its intellectual property. Among defendants, the company named Apple, Broadcom, Mediatek, NVIDIA, Qualcomm, Xilinx and many others. GlobalFoundries seeks damages from TSMC and wants courts to ban shipments of products that use infringing semiconductors into the USA and Germany.

GlobalFoundries vs. TSMC et al
Fabless Chip Designers Consumer Product Manufacturers Electronic Component Distributors

Quite naturally, TSMC denies any allegations and claims that it will defend itself in courts. The company stresses that it spends billions of dollars on R&D and has been granted 37,000 patents worldwide. Typically, high-tech companies counter-sue each other in patent infringement cases, so it will not be surprising if TSMC decides to sue GlobalFoundries. In the end, this is what patents are for. Meanwhile, unlike GlobalFoundries, TSMC will unlikely sue fabless designers of semiconductors that use the former’s services to a large degree because the vast majority of chip developers are it slients.

The statement by TSMC reads as follows:

TSMC is in the process of reviewing the complaints filed by GlobalFoundries on August 26, but is confident that GlobalFoundries’ allegations are baseless. As a leading innovator, TSMC invests billions of dollars each year to independently develop its world-class, leading-edge semiconductor manufacturing technologies. As a result, TSMC has established one of the largest semiconductor portfolios with more than 37,000 patents worldwide and a top 10 ranking for US patent grants for 3 consecutive years since 2016. We are disappointed to see a foundry peer resort to meritless lawsuits instead of competing in the marketplace with technology. TSMC is proud of its technology leadership, manufacturing excellence, and unwavering commitment to customers. We will fight vigorously, using any and all options, to protect our proprietary technologies.

    Absolutely sue them yes!!!!

    Amounts!!! of Intellectual Property China (and others) have stolen is...
    well, can't measure it even if you tried your hardest. Not just US but
    Europe too, ban them completely from selling any tech in US and Europe.
    These thieves, especially thieving regime of China, continue destroying
    whole industries by the means of steal-and-copy-counterfeit art.
    Korea used to be like that as well, and yes some will rush to shout, as if it was a discovery, that TSMC is Taiwanese... really...

    I wonder how much, and I worry that everything, have do to with this ill behaviour Chinese mentality. I cannot recall who and how exactly that study, or an experiment rather, was done, (I'm old and my memory can fool me) you must have heard of it. They invited anonymously people of varied nationalities and it was something about the money I think, cash, where they let people take and keep I think some cash. There was some trick to it I cannot remember, but... !!! Surprise surprise, most truthful were Russians.. and Chinese??? the opposite end of the spectrum they were.

    So you’re saying that they should be sued because Chinese companies often steal IP, while simultaneously admitting that they aren’t a Chinese company? Nice little contradiction there.

    Nearly every major motherboard and graphics card company is based in Taiwan. If Taiwanese companies wanted to steal from the top computer electronics manufacturers, they’d need to steal from other Taiwanese companies.

    We are speaking of particular manufacturing technologies, other Taiwanese companies have not relevance here. GF is claiming some IP infringiments of Common Plataform IP patents portfolio.
    In fact GF is not calling in courts Samsung.
    Anyway the fast TSMC acceleration in Fin Fet processes development is suspect. Sometimes stealing tech from other Companies halve the developing times. For example China is an artist in this pratice.

    I am pretty sure Samsung cross-licensed a bunch of patents considering the GF 14nm is largely the one Samsung developed. Reply

    ah.. you did not read at all or.. you did not read.
    I know, I knew some would shout that TSMC is Taiwanese and not Chinese both of which are not the same, to which my proposed implied reply was - yes, they are the same! (do not even bother to ask continental Chinamen for you will get yourself in trouble).
    And it's that Chinese mentality which is root of the problem. Almost everybody lies but over there in China, everything suggests, it's a "national" issue.

    Lastly, I hear you must be young, maybe very very young, you can this one simple thing - ask yourself (home work properly) how old semiconductor industry and about its origins (here you'll learn about places in Asia) and where was and what was China & Taiwan doing... lets say somewhere half way of the evolution of this industry.
    My man that stuff does not go just 10 or 15 years back!

    There is no 'Taiwan'. Only Republic of China and People's Republic of China. Both of them are Chinese and they share characters of Chinese. However, I don't see why this is relevant here. Reply

    Newsflash: US and Imperial Germany stole patents from British Empire. Japan and South Korea stole patents from the "West". China stole patents from all of the above. Every advanced industrial nation had a phase when they stole patents and know how from others. Reply

    Yes, true, but my man... If steal-copy-counterfeit art is something one can do for a living then China does it on an industrial scale!!

    I could tell you guys first-hand real stories but work I do is for public sector and I'm not sure I'm allowed to go into more details which I'd love to do.

    "If steal-copy-counterfeit art is something one can do for a living then China does it on an industrial scale!!"

    don't get too high on your horse. if red-blooded Americans hadn't stolen virtually everything from the Brits in the 19th century, the USofA would just be another 3rd world country.

    No high horse for me my man, me, I was born and since lived most of my live in 3rd world county. Reply
