Technology Licensing

The list shown here includes the most popular Microsoft Technology Licensing (MTL) programs. If you are interested in licensing not found on this list, please contact MTL Licensing and include the name of the specific technology you are interested in licensing.
  • MTL offers a flexible Intellectual Property (IP) licensing program that provides broad coverage under Microsoft’s patent portfolio for certain devices running the Android platform.

  • Several devices, from portable computers and personal digital assistants (PDAs) to mobile phones and video cameras, use liquid crystal display (LCD) technology to render images on a screen. Before these innovations existed, the smallest level of detail that a computer could use was a single pixel. With ClearType font technology, LCD monitors now can display features of text as small as a fraction of a pixel in width.

    The result is that the words on a computer screen now look almost as sharp and clear as those printed on a piece of paper. ClearType improves readability of text on LCD displays so that words on the screen appear almost as sharp and clear as words on a printed page. Resolution improvements also increase the sharpness of tiny details in text that is displayed. This makes it easier for the user to read over long durations.

  • Exchange ActiveSync is a communication protocol that allows mobile devices running Windows Mobile to synchronize email, calendar, contacts, and tasks (known as PIM, Personal Information Manager) over the air with the Microsoft Exchange Server. The sync protocol is the language spoken between the mobile device and messaging server to synchronize objects. The device will have its own email, contacts, calendar and task (PIM – Personal Information Manager) application, which provides a user interface and data storage. Syncing is the process of reconciling differences between data stored on the mobile device and stored on the Exchange Server. Both the mobile device and the Exchange Server maintain their own collections of objects and track changes made since the last sync. The mobile device may initiate a new sync by sending a set of updates to the Exchange Server and requesting the Exchange Server respond with its own updates. The Exchange server processes updates it receives, resolves any conflicts, and sends its list of changes back to the mobile device. Microsoft licenses the patents for Exchange ActiveSync please contact us for more information.

    Exchange ActiveSync is available on both Windows Mobile-based devices and Exchange ActiveSync-enabled devices offered through Microsoft partners. By taking advantage of Exchange ActiveSync through compatible devices and software, users can avoid added costs of middleware or service fees.

    Please visit Microsoft Exchange Features - Email for Business page for more information about Microsoft's implementation of Exchange ActiveSync, and the Exchange ActiveSync Overview and Exchange Server Protocol Documents for additional information about the protocol.

  • MTL offers a flexible patent licensing program in response to an increase in the industry's interest in licensing our Extended File Allocation Table (exFAT) file system. Use of media across different products is increasing the need for a common file system for data sharing across multiple platforms and products. exFAT facilitates this interchange as it is capable of handling large file sizes and can be implemented on any platform. Windows Vista SP1 and later desktop operating systems include the exFAT file system and a redistributable package will be available for Windows XP, enabling seamless file exchange between desktop computers and personal devices, such as digital cameras and mobile phones. Additionally, exFAT is relatively simple and easy to implement. The exFAT system offers the following advantages:

    • Enables future growth in media capacities, increasing support from 32GB up to 256TB.
    • Handles more than 4000 RAW images, 100 HD movies, or 60 hours of HD recording in a single directory.
    • Speeds up file saves of SDXC cards to achieve their full 300MBps speed using modern storage allocation techniques.
    • Supports interoperability with future desktop OSs.
    • Provides an extensible format, including OEM-definable parameters to customize the file system for specific device characteristics.

    Extended file allocation table (exFAT) is a new file system that is better adapted to the growing needs of mobile personal storage. The exFAT file system not only handles large files, such as those used for audio/video media; it enables seamless data portability between desktop PCs and consumer electronic devices allowing easy interchange between the two. Inheriting its base from FAT, exFAT can be implemented with minimal effort. In addition, you can choose to add transaction support to your exFAT implementation (TexFAT) to ensure transaction-safe operations. SD Card Association adopted exFAT file system for its latest high capacity high speed SDXC card. Memory Stick XC™ Series adopted exFAT file system for its new memory stick cards enabling high speed data storage.

    Please note that open source or other publicly available implementations of exFAT do not include a patent license from MTL. For licensing information, contact MTL Licensing for further details.

  • RTVideo and RTAudio codecs are real-time Microsoft video and audio codecs developed for the Windows Live Messenger, Microsoft Office Communications Server 2007, Microsoft Office Communicator 2007, and Microsoft Office Live Meeting 2007 platforms. The RTAudio codec is designed for both high-quality wideband and narrowband voice over IP (VoIP) applications, including applications such as games, audio conferencing, and wireless applications. The RTVideo codec provides high-quality, efficient, and robust real-time video communication over IP networks. The RTVideo codec is based on the SMPTE VC-1 codec and includes system-level enhancements for recovery of packet loss on IP networks.

    RTVideo and RTAudio codecs allow third-party implementation of the codecs to expand on interoperability with Microsoft Real-Time Communication platforms. The RTAudio encoder is capable of encoding single-channel (mono), 16-bit per sample audio signals. It can be configured to operate in narrowband (8-kilohertz [kHz] sampling rate) or wideband modes (16-kHz sampling rate). It also has a built-in adaptive jitter control and advanced packet loss concealment modules. High-quality video and audio can be delivered between the Microsoft Real-Time Communication platform and other standards-based video conferencing solutions.
