Buoying Vessels Over Shoals. In 1849, Abraham Lincoln was awarded Patent No. 6469 (drawing and large TIFF files of pages 1, 2, and 3 of the actual patent) for a device for raising stuck riverboats off sand bars. The model he submitted with the patent application is at the National Museum of American History; who made the model is a bit of a mystery. Lincoln is the only United States President to hold a patent. (Other Lincoln-related patents, including the patent for Lincoln Logs.)

Macromedia claims it owns Adobe patent "Software-maker Macromedia Inc. is claiming it owns the patent to Adobe Systems Inc.'s popular Photoshop program, according to a suit filed in federal court Friday." Macromedia is alleging that in 1998 it patented technology used by Photoshop. Couldn't this only be web-based technology, since Photoshop was around long before 1998?
