CAMBRIDGE, England and SAN FRANCISCO, September 2, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that Clifford
Chance has chosen Autonomy Introspect, a top-ranked processing, review and
production solution for complex litigation and regulatory investigations.
Clifford Chance is one of the world's leading law firms, with 29 offices in
20 countries and some 3,200 legal advisers. Autonomy Introspect was selected
thanks to its unmatched meaning-based capabilities including integrated
keyword and conceptual search, near-duplicate analysis and meaning based
coding, massive, petabyte scalability, and the ability to process and
understand all data types and languages. Available as hosted, onsite and
hybrid solution, Autonomy Introspect uniquely offers the ability to process
audio, video and rich-media alongside other Electronically Stored Information

"Autonomy Introspect provided the solution which we needed in handling
complex proceedings with both voice and electronic data," commented Denis
Brock, litigation partner at Clifford Chance. "I have been impressed by the
quality of the product and the service delivery of Autonomy; I anticipate
that, for matters in the future, Autonomy will be my preferred choice."

Powered by Autonomy's meaning-based technology, the Intelligent Data
Operating Layer (IDOL), Autonomy Introspect addresses every stage of complex
litigation and offers both full EDD processing with intelligent filtering as
well as advanced review and production. With ten of the top ten law firms as
customers, Introspect is the de-facto standard for advanced document review.
IDOL's advanced analytics provide automated clustering, near-duplicate and
meaning based coding, message tracing and automatic foldering to enable users
to review documents in an efficient, non-linear fashion. Additionally, IDOL
can identify similar documents even if they have different authors or file
formats, helping ensure completeness of the results and a dramatic increase
in both the speed and efficiency of the document review process.

Autonomy Introspect offers unique features and capabilities including:

    - Direct discovery processes on all data types including audio and
      multiple languages
    - Meaning Based Coding - Autonomy's concept-based pattern recognition
      technology automatically learns how reviewers code documents to
      automatically code remaining documents
    - Rapid review using sophisticated near-duplicate processing and coding
      by subject matter or cluster and workflow
    - Simple visualizations to trace custodians' messages over time
    - View of communication links between custodians instantly
    - The most robust security model in the industry
    - Automatic document summaries
    - Web-based, intuitive user interface to simplify training for new and
      infrequent users

"In today's highly litigious environment, law firms need an end-to-end
technological platform that enables them to bring meaning to all data,
despite its format or location, for efficient, cost-effective, reliable and
defensible processing, review and production," said Mike Sullivan, CEO,
Autonomy Protect, Enterprise Solutions. "Thanks to IDOL, Autonomy is the only
company able to meet these requirements. We are delighted that Clifford
