[edit] IBM

[edit] Fat lines

Scant details can be found in a Forbes article.[1]

...IBM's notorious "fat lines" patent: To turn a thin line on a computer screen into a broad line, you go up and down an equal distance from the ends of the thin line and then connect the four points. You probably learned this technique for turning a line into a rectangle in seventh-grade geometry, and, doubtless, you believe it was devised by Euclid or some such 3,000-year-old thinker. Not according to the examiners of the USPTO, who awarded IBM a patent on the process.

[edit] Changing email font colours

Mentioned in a Slashdot submission.[2] See also, the patent itself.[3]

For example, an email created in the U.S. in red font to indicate urgency or emphasis might be mapped to a more appropriate color (e.g., blue or black) for sending to Korea.

[edit] Microsoft

[edit] Page up, page down

US patent no 7,415,666, granted August 19, 2008.

Title: Method and system for navigating paginated content in page-based increments

Abstract:

A method and system in a document viewer for scrolling a substantially exact increment in a document, such as one page, regardless of whether the zoom is such that some, all or one page is currently being viewed. In one implementation, pressing a Page Down or Page Up keyboard key/button allows a user to begin at any starting vertical location within a page, and navigate to that same location on the next or previous page. For example, if a user is viewing a page starting in a viewing area from the middle of that page and ending at the bottom, a Page Down command will cause the next page to be shown in the viewing area starting at the middle of the next page and ending at the bottom of the next page. Similar behavior occurs when there is more than one column of pages being displayed in a row.

[edit] The IsNot operator

The author of the patent has stated that his strictly personal view, software patents should not exist and that they "generally do much more harm than good".[1]

[edit] FAT and shortening filenames

[edit] Double-clicking

US patent no 6,727,830, granted April 27, 2004 to Microsoft.

Title: Time based hardware button for application launch

Abstract:

A method and system are provided for extending the functionality of application buttons on a limited resource computing device. Alternative application functions are launched based on the length of time an application button is pressed. A default function for an application is launched if the button is pressed for a short, i.e., normal, period of time. An alternative function of the application is launched if the button is pressed for a long, (e.g., at least one second), period of time. Still another function can be launched if the application button is pressed multiple times within a short period of time, e.g., double click.

To see the details of this on the USPTO's website, use their search page and search for patent number 6,727,830.
