Several Chinese display manufacturers, including BOE, CSOT, Tianma, and Visionox, have joined forces to invalidate a patent owned by Samsung Display in the United States. The move comes as a response to Samsung Display’s previous attempts to halt imports of third-party displays that might infringe upon its patented technologies.
The Motive Behind the Challenge: Chinese Display Manufacturers’ Response to Samsung’s Patent Actions
The patent in question is U.S. Patent No. 7,414,599, which pertains to an “Organic Light Emitting Display (OLED) Device Pixel Circuit and Driving Method.” This particular patent was part of Samsung Display’s complaint filed with the US International Trade Commission late last year, seeking to prevent the importation of OLED panels that allegedly violated their patents and technologies.
Rather than confronting the Chinese manufacturers directly, Samsung Display opted to target importers. However, this approach seems to have provoked a retaliatory response from the Chinese display makers. By seeking to invalidate Samsung Display’s OLED patent, BOE, CSOT, Tianma, and Visionox may inadvertently imply their involvement in developing displays utilizing Samsung’s technologies without obtaining proper licenses.
This ongoing dispute began in early May when BOE initiated a series of patent infringement lawsuits against Samsung and its subsidiaries in China. Interestingly, these lawsuits targeted divisions unrelated to display technologies, such as Semiconductor, Investment, and Vision. Now, the Chinese display manufacturers are collectively aiming to invalidate one of Samsung Display’s OLED patents in the United States.
It’s worth noting that the trial for patent invalidation is yet to commence, as the Patent Trial and Appeal Board is currently evaluating whether to accept the claim. Further developments, in this case, will shed light on the potential ramifications for the involved parties and the wider display manufacturing industry.
