Microsoft vs. Corel: The Slider Design Patent

December 31, 2015

Microsoft recently sued Corel over a variety of items recently. One of those items is the slider shown below.


While most of you are most familiar with CorelDRAW (which has had variations on sliders for many versions), this lawsuit is targeted at Corel Home Office which includes Corel WordPerfect.

The folks at Electronic Frontier Foundation have written about this in an article titled Stupid Patent of the Month: Microsoft’s Design Patent on a Slider. If you want to read the actual legal filing, a link is provided in their article.

Should Microsoft prevail, Federal Circuit Court law would entitle Microsoft to all of Corel’s profits for the entire product even though the slider is only a very small part of the product.

Give the lawsuit a read and then leave a comment on this post (not via e-mail) and share your thoughts on this lawsuit.
