You may not be familiar with the company Corel, but one of the program known to me is CorelDRAW, a PhotoShop alike program for drawing. So what Corel done that have possibly make Microsoft angry? Apparently Corel’s office suites has copied many of Microsoft’s patents and Slider UI is one of them according to Microsoft.
Patents are usually properties that one company has the rights to while others are not permitted to copy and use it. Using someone else’s patents can often leads to lawsuit just like Apple vs Samsung lawsuit which will never stop.
While back in last December the 18th, Microsoft claims that Corel’s office software copied several patents filed by Microsoft. Microsoft also went on and said that the company’s program totally copied Microsoft Office in it’s interface and even has a “Microsoft Word/Excel mode” for users to get used to the program itself.
Slider UI is one of many elements of Microsoft office that allows you to slide the slider from one direction to another to zoom documents, but also being used on many many 3rd party programs and games.
To add insult to injury:
So really Microsoft? Really? If Corel is found to have infringed on Microsoft’s patents, even from a simple Slider UI. Microsoft can profit from Corel’s office suites by the Federal Circuit law.
