For those who watch graphics manufacturers closely, you may have noticed NVIDIA changed its corporate logo over the weekend. A quick search in the US Trademark Electronic Search System (TESS) shows that this new logo design is not officially processed yet.
The logo now appears to show the corporate trademark in all capital letters -- at least more so than it did before. The previous logo appeared to show the trademark written as "nVIDIA," but the company had changed the official trademark to all capital letters (NVIDIA) several years ago.
The image below shows both the old (bottom) and the new (top) design.
