Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Word of the Day: patent troll

Margaret Rouse Margaret Rouse Profile: Margaret Rouse


“The killer horror about software patents and their even vaguer cousins, business method patents, is that there are so many of them out there. So many of them are so stupidly broad that any software you write will almost certainly violate someone’s patent.” — Robin Miller

Today’s WhatIs.com Word of the Day is patent troll, an individual or an organization that purchases and holds patents for unscrupulous purposes such as stifling competition or launching patent infringement suits.

Patents frequently describe a general concept rather than a product or process; furthermore, the patent may not define what it protects in adequately precise terms. Both of those situations render the patent system vulnerable to abuse. In 2011, for example, a patent assertion entity called Innovatio threatened to sue 8,000 hotels, stores and coffee shops in the United States, claiming that the use of Wi-Fi infringed upon 17 of its patents.

Word of the Day: UE virtualization

Margaret Rouse Margaret Rouse Profile: Margaret Rouse


“With nonpersistent virtual desktops, a single disk image is shared among many users. As each user logs in, he gets a clone of the master desktop and then that clone is customized on demand with app virtualization or with user environment virtualization.”Brian Madden

Today’s WhatIs.com Word of the Day is user environment virtualization, the abstraction of personalized computer settings from an end user’s operating system and applications. User environment virtualization software allows desktop and application virtualization users to keep personalized settings — such as desktop wallpaper and browser bookmarks — even though the operating system and software applications come from a standardized template or golden image shared by everyone. These persistent settings can follow users from session to session and from one physical machine to another in a nonpersistent virtual desktop infrastructure. Continued…
