investigation, there are no actions, suits, investigations, claims, or proceedings pending, in progress, or threatened in a written document, relating in any way to the Assigned Patent Rights.  Except as set forth in paragraphs 4.4 and 4.5 above, or on Exhibit G or Exhibit I, there are no existing contracts, agreements, options, commitments, proposals, bids, offers, or rights with, to, or in any person to acquire any of the Assigned Patent Rights.
 
6.3 Existing Licenses and Obligations.  There is no obligation imposed by a standards-setting organization to license any of the Patents on particular terms or conditions.  Except as set forth in paragraphs 4.4 and 4.5 above and except for the nonexclusive licenses, settlements, and other agreements listed on Exhibit G, no licenses under the Patents, or interest or rights in any of the Assigned Patent Rights have been granted or retained.  None of the licenses or rights in the licenses listed on Exhibit G is an exclusive grant or right and, except as expressly noted on Exhibit G, each such license is nontransferable and nonsublicensable.
 
6.4 Restrictions on Rights.  Except as set forth on Exhibit G, and to the best of Seller’s knowledge, formed after reasonable due diligence and investigation, Purchaser will not be subject to any covenant not to sue or similar restrictions on its enforcement or enjoyment of the Assigned Patent Rights or the Abandoned Assets as a result of any prior transaction related to the Assigned Patent Rights or the Abandoned Assets.
 
6.5 Validity and Enforceability.
 
(a) Except for actions taken by a respective patent office or patent authority, none of the Patents or the Abandoned Assets has ever been found invalid, unpatentable, or unenforceable for any reason in any administrative, arbitration, judicial, or other proceeding.
 
(b) Except as set forth on Exhibit I, and to the best of Seller’s knowledge, formed after reasonable due diligence and investigation, Seller does not know of and has not received any notice or information of any kind from any source suggesting the invalidity, unpatentability, or unenforceability of any claimed subject matter within the Patents or Abandoned Assets that has ultimately been allowed, granted, or otherwise deemed patentable by a respective patent authority or patent office, with the exception of rejections, objections, or other deficiencies identified by such patent authority or patent office.
 
(c) Except as set forth on Exhibit I, and to the best of Seller’s knowledge, formed after reasonable due diligence and investigation, Seller does not know of and has not received any notice or information of any kind from any source suggesting the invalidity, unpatentability, or unenforceability of claims contained within any of the patent applications within the Patents that have not yet been subject to substantive examination by a respective patent office or patent authority, with the exception of rejections, objections, or other deficiencies identified by a respective patent authority or patent office.

If any of the Patents is terminally disclaimed to another patent or patent application, all patents and patent applications subject to such terminal disclaimer are included in this transaction.  To the extent “small entity” fees at the time of such payment were paid to the United States Patent and Trademark Office for any Patent, such reduced fees were then appropriate because the payor qualified to pay “small entity” fees and specifically had not licensed rights in the Patent to an entity that was not a “small entity.”
 
6.6 Conduct.  To the best of Seller’s knowledge, formed after reasonable due diligence and investigation, none of Seller, any prior owner or their respective agents or representatives have engaged in any conduct, or omitted to perform any necessary act, the result of which would invalidate any of the Patents or hinder their enforcement, including, without limitation, misrepresenting the Patents to a standard-setting organization.
 
6.7 Enforcement.  Except as set forth on Exhibit I, and to the best of Seller’s knowledge, formed after reasonable due diligence and investigation, (a) Seller has not put a third party on notice of actual or potential infringement of any of the Patents or the Abandoned Assets; (b) Seller has not invited any third party to enter into a license under any of the Patents or the Abandoned Assets; and (c) Seller has not initiated any enforcement action with respect to any of the Patents or the Abandoned Assets.
 
6.8 Patent Office Proceedings.  Except as set forth on Exhibit I, and to the best of Seller’s knowledge, formed after reasonable due diligence and investigation, none of the Patents or the Abandoned Assets has been or is currently involved in any reexamination, reissue, interference proceeding, or any similar proceeding in foreign countries, and no such proceedings are pending or threatened.
 
6.9 Fees.  All maintenance fees, annuities, and the like due or payable on the Patents have been timely paid.  For the avoidance of doubt, such timely payment includes payment of any maintenance fees for which the fee is payable (e.g., the fee payment window opens) even if the surcharge date or final deadline for payment of such fee would be in the future.
 
6.10 Abandoned Assets.  According to each applicable patent office, each of the Abandoned Assets has expired, lapsed, or been abandoned or deemed withdrawn.

PRESS RELEASE

After execution by both parties:
 
AVISTAR COMMUNICATIONS MONITIZES PATENT PORFOLIO THROUGH
 
TRANSACTION WITH INTELLECTUAL VENTURES FUND 61 LLC
 
Agreement in principle calls for Avistar to sell the majority of its patent portfolio to Intellectual
 
Ventures Fund 61 LLC for the sum of $$$’s
 
(a)  
San Mateo, Calif., November 30, 2009 – Avistar Communications Corporation (www.avistar.com), a leader in unified visual communications solutions, today announced that it has entered into an agreement with Intellectual Ventures Fund 61 LLC to sell the majority of its patents as part of a strategy to monetize its patent portfolio and continue investment into its product business.
 
 
Highlights of the transaction are as follows:
 
·  
Avistar receives an upfront payment of $$$’s.  This allows Avistar to further invest in its product strategy and reinforces its cash position.
·  
Avistar receives a full grant back license under the portfolio ensuring that its products are protected under these patents
·  
Avistar is no longer adverse to the firms that it has previously put on notice
 
Bob Kirk, Chief Executive Officer of Avistar, said, “The transaction with Intellectual Ventures Fund 61 LLC is an important milestone for Avistar.  This allows us to find the right vehicle for these patents to be represented in the market.  It allows Avistar to focus on what we do best, that is deliver industry leading and award winning products to our partners, clients and the visual communications industry.  This also removes what has been a significant distraction for the team and our operation in general, while providing us the capital to more aggressively invest in our business.”
 
The agreement in principle is expected to close by end of November after remaining due diligence and process has completed.
