As of today a federal appeals court is upholding the judgement to bar Microsoft from selling current versions of Word and Office. The question is, what does the patent actually entail? The original patent can be summarized as covering a "method and system for manipulating the architecture and the content of a document separately from each other." With this broad an abstract, it appears that the patent could affect a lot more than simple word processing. But, as with all patents, the devil is in the details.

What exactly from Office Web Apps and Office Mobile 2010 can you use on your mobile right now and what will be available when the product ships next spring?

Mary Jo Foley does the best job of outlining what is happening here. Let's take a sky high look and see if we can make sense of things so you know what to do if you really have an interest in giving Office a try on the mobile.

Office Web Applications, the browser-based versions of Microsoft Word, Excel, PowerPoint, and OneNote, are now being made available to more users according to a post on the Windows Live Team blog. The online office suite, which began its initial alpha testing (in Microsoft terms, it's called a "Technical Preview") in mid-September, was originally made available to only a limited number of users. Today, the Technical Preview is opening up, allowing more people to try the Web Apps, Microsoft's first attempt at porting their desktop Office software to the cloud.

Today at its Wordwide Partner Conference in New Orleans, Microsoft announced that the Microsoft Office suite has reached the 'technical preview' milestone, and that starting today the company will open up the Office beta program to a larger number of users. While a new version of Office is obviously big news for a lot of users, the really interesting part of the announcement is that Microsoft is also releasing more details about the Office Web applications - which are lightweight, browser-based versions of Word, Excel, PowerPoint, and OneNote (Microsoft's note-taking tool). Beta testers can expect invites for the Office Web applications to go out in August.

Come July, ThinkFree, the web office provider which first added mobile access in 2008, will unveil the only complete Office suite for the Android OS.

To date, the official Android Market has had slim pickings when it comes to document editing, with the majority of apps being simple notepads. For enterprise users, so many of whom still rely heavily on Microsoft Office, a notepad simply won't cut it.

Today, the web office company Zoho, whose line of products competes with other web applications like Google Docs and Gmail as well as desktop-based suites like Microsoft Office, has launched a new product: Zoho Gadgets. With these gadgets, data from Zoho applications can be integrated into Facebook, Gmail, iGoogle, Orkut and other online networks. Because the gadgets are built using the OpenSocial standard, they can be supported by any OpenSocial compatible network.

Two former Microsoft employees, Shan Sinha, a former Microsoft SharePoint and SQL Server strategist, and Alex DeNeui, also a SQL strategist, are attempting to do what (so far) Microsoft has not: compete head-on with Google Docs by transforming Microsoft Office into online collaboration suite. To do so, they've launched a company called DocVerse, an early-stage startup that aims to simply document sharing and collaboration.

Now that we have online office suites like Google Docs, Zoho, and even Adobe's Acrobat.com, you may not have much desire to go and check out yet another would-be Microsoft Office killer. However, Shutterborg, a new online word processor does one thing really well which makes it a unique tool in this space: it lets you open any URL on the internet and edit it like an Office document.

It's been a little bit more than two years now since Google merged Google Spreadsheets with Writely, and while there has been a lot of talk about online office suites, the latest data from Compete indicates that Google Docs & Spreadsheets is still mostly attracting casual users who don't spend a lot of time with the service. Also, one of the most interesting data points in the Compete study is that only about 58% of unique visitors to Docs & Spreadsheets actually used one of the available apps after visiting the site. A large number of users never makes it past the marketing pages.
