Section 01 / Executive Briefing
- The Munich Regional Court closes the German leg of the Innoscience-Infineon GaN dispute on June 19 — and the outcome rhymes with the US ITC's. Infineon prevailed on two further claims, but, as in the US, the court found infringement only as to discontinued legacy products; Innoscience's current commercial product line was again found to fall outside the asserted patents' scope.
- All three jurisdictions in the global GaN patent war have now ruled, and the pattern across them is genuinely instructive. China delivered an outright, currently-effective sales ban against Infineon (Issues 09–10); the US and Germany each delivered narrower, split outcomes against Innoscience confined to discontinued products. The same underlying technology dispute produced three meaningfully different commercial outcomes depending on jurisdiction.
- No major new Mainland legislative or policy announcements were identified this week — a comparatively quiet week administratively, following two consecutive weeks of significant CNIPA and SPC activity (Issues 09–10).
- Hong Kong and Taiwan continue to be shaped by the same semiconductor IP currents driving this week's lead story, reinforcing themes raised across Issues 09 and 10.

Munich Regional Court Rules for Infineon — But Confines Infringement to Discontinued Legacy Products
Munich Court Closes the German Front of the Global GaN Patent War, Completing a Remarkably Consistent Three-Jurisdiction Pattern
On June 19, 2026, the Munich I Regional Court (Landgericht München I) ruled in Infineon's favour on two further claims — one patent and one utility model — against Innoscience, in the German leg of the long-running global GaN patent dispute. Infineon called the result its "third and fourth legal defeat" of Innoscience in German proceedings, following an earlier August 2025 ruling and adding to its successes in the U.S. ITC. The court ordered Innoscience to cease manufacturing, selling, or marketing the infringing products in Germany and to pay damages.
Critically, however, Innoscience's own statement on the ruling — consistent with the structure of the US ITC outcome — clarifies that the German court found infringement only with respect to a limited set of discontinued legacy products (certain packaged 650–700V transistors), concerning the German counterpart of the same patent family at issue in the ITC's '481 patent finding. Innoscience maintains that its currently marketed GaN power device products fall outside the scope of the asserted German patents and may continue to be commercialised in Germany without restriction. Further German proceedings, including Innoscience's pending invalidity challenges to the asserted patent, remain ongoing.

Suzhou Intermediate People's Court (China) finds Infineon infringed two Innoscience GaN patents; orders sales halt and RMB 10M damages. (Issue 09)

US ITC final determination: Innoscience's current products do not infringe; only discontinued legacy products infringed one Infineon patent — limited exclusion order. (Issue 10)

SPC (China) rejects Infineon's reconsideration request — Suzhou sales ban against Infineon final and enforceable. (Issue 10)
June 19, 2026
Munich Regional Court (Germany) rules for Infineon on two further claims, but — echoing the ITC — confines the finding to discontinued legacy Innoscience products. German invalidity proceedings continue.
With rulings now in hand from all three major jurisdictions, the comparative pattern is striking and instructive for any company managing parallel global patent disputes: China delivered an outright, currently-effective sales injunction against Infineon covering active commercial products, while the US and Germany each delivered narrower findings against Innoscience, confined specifically to discontinued legacy product lines and leaving each company's respective current commercial offerings largely intact in the other's market. Rather than one company simply "winning" or "losing" globally, the dispute illustrates how the same underlying technology and overlapping patent families can yield materially different commercial consequences depending on the forum, the specific claims asserted, and the precise product generations at issue.
Companies litigating parallel patent disputes across China, the US, and Europe should resist the temptation to read a single jurisdiction's outcome as predictive of the others — as this dispute demonstrates, courts in different systems applying different claim constructions to overlapping but non-identical patent families can reach genuinely different conclusions about which product generations infringe. Portfolio and product-line documentation that clearly distinguishes current from discontinued offerings, as Innoscience appears to have maintained, can materially narrow the practical commercial impact of an adverse finding.

Taiwan's Compound Semiconductor Ecosystem Watches the GaN Dispute's Conclusion with Direct Commercial Interest
With all three jurisdictions in the Innoscience-Infineon dispute now having ruled, Taiwan's foundries, packaging houses, and power semiconductor design firms — already flagged in Issue 10 as structurally exposed to this category of compound semiconductor patent contest — can now assess the dispute's actual rather than anticipated commercial contours. Because each ruling distinguished current from discontinued product lines rather than imposing a blanket prohibition, the practical disruption to global GaN supply chains, including those running through Taiwan, appears more contained than an outright cross-jurisdiction sales ban would have produced. Taiwan-based companies sourcing or supplying GaN components from either party should nonetheless confirm which specific product generations are implicated in each ruling before assuming continuity of supply.

The GaN Dispute's Conclusion Reinforces the Case for Hong Kong as a Coordination Venue in Multi-Jurisdiction IP Disputes
Now that the Innoscience-Infineon dispute has produced rulings in China, the US, and Germany within a roughly six-week span — each with materially different scope and commercial effect — the episode stands as a clean illustration of the theme raised across Issues 08 through 10: companies facing simultaneous patent disputes in multiple jurisdictions benefit from a coordinated global strategy rather than treating each forum in isolation. Hong Kong's continued positioning as a neutral venue for the commercial and licensing conversations that typically follow a multi-front litigation campaign of this kind remains relevant regardless of how any individual jurisdiction's litigation concludes.
