Linklaters Selects Autonomy's IDOL for Enterprise Search

Easy Search Interface and Conceptual Search To Boost Productivity at Leading Global Law Firm

CAMBRIDGE, England and SAN FRANCISCO, May 4, 2011 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that Linklaters,
a leading global law firm with 26 offices and around 5,000 employees
worldwide, is implementing a new user-orientated enterprise search platform,
powered by Autonomy's cornerstone technology, IDOL (the Intelligent Data
Operating Layer), to help its lawyers work more productively.

Knowing its vast volumes of internal information to be a crucial asset to
the firm, Linklaters wanted to tailor its internal search tool to the key end
users, its lawyers, in order to boost productivity. In a project spearheaded
by Autonomy and longstanding Autonomy partner, Okana, now part of the Realise
group, Linklaters selected Autonomy's IDOL for enterprise search due to its
unique conceptual abilities, language independence, scalability and ability
to connect to virtually every data repository.

"The genesis of this project was to provide quick and easy access to our
wealth of internal knowledge for our lawyers," said Suzanne Fine, Global Head
of Knowledge & Learning, Linklaters. "Partnering with Autonomy and Okana has
given us the opportunity to offer a simple search solution across Linklaters'
global network."

Unlike legacy approaches, Autonomy's enterprise search solution is also
designed to put the users in complete control of their information
environment and enable them to explore the information relevant to them
through an easy-to-use search interface.

"This project is about turning the idea of enterprise search on its head,
and creating an interface that is focused on the very people who consume the
information - our lawyers," said Gerard Bredenoord, Head of Knowledge,
Linklaters. "Okana's Sense User Interface combined with Autonomy's IDOL
enterprise search provides our lawyers with an intuitive interface designed
with them in mind, allowing both implicit and active conceptual searches that
deliver only the most relevant information."

IDOL is revolutionary in its ability to ingest and form an understanding
of all information, whether structured, semi-structured or unstructured, and
use this to extract meaning across different formats, languages and
locations. Furthermore, Autonomy delivers unmatched security infrastructure,
to ensure that confidential documents are correctly controlled and user
entitlement levels respected.

"This is another great example of a leading law firm that is embracing
IDOL's conceptual search capabilities and user-focused interface in order to
deliver solid improvements in efficiency," said Nigel Hutchinson, VP Autonomy
Power solutions EMEA. "By securing the firm's knowledge on one single
platform for easy and intelligent retrieval - providing users with precisely
the information they need - Linklaters is helping its lawyers avoid
duplication of effort, unlock information assets that were previously
difficult to access and save time, while freeing them up to focus on
higher-value activities."

Linklaters is using IDOL to index some 250,000 curated legal knowledge
documents, rendering a subset of key, approved legal knowledge searchable for
over 2,200 lawyers globally.
