Microsoft loses anti-piracy patent case

A Rhode Island jury found the company infringes on a patent held by Uniloc

A jury in Rhode Island found Microsoft guilty of patent infringement, ordering it to pay US$38 million to Uniloc, the patent holder.

Initially filed in 2003 in the U.S. District Court for the District of Rhode Island, the suit alleges that Microsoft's product activation system infringes on a patent held by Uniloc.

The jury decided that the patent is valid and that Microsoft willfully infringes it.

The software giant still thinks otherwise and intends to appeal the decision.

"We believe that we do not infringe, that the patent is invalid and that this award of damages is legally and factually unsupported. We will ask the court to overturn the verdict," the company said in a statement.

Microsoft's product activation process aims to reduce piracy by requiring people to activate their software, tying it to a particular machine in the process.

Users can then reinstall the software repeatedly on that machine, but can't share the software with other people and PCs.

Uniloc sells technology that software developers use to offer flexible licensing terms, such as trial periods.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
