   Vringo, Inc. : VRINGO PROVIDES UPDATE ON U.S. PATENT & TRADEMARK OFFICE
                                 PROCEEDINGS

NEW YORK - May 3, 2013 - Vringo, Inc. (NASDAQ: VRNG), a company engaged in the
innovation,  development   and  monetization   of  mobile   technologies   and 
intellectual property, today  provided an  update on proceedings  at the  U.S. 
Patent and  Trademark Office  (USPTO) regarding  patents owned  by its  wholly 
owned subsidiary, I/P Engine, Inc. This summary is qualified in its  entirety 
by the USPTO proceedings.

Background

I/P Engine asserted  two patents  originally acquired from  Lycos, Inc.,  U.S. 
Patent Nos.  6,314,420 and  6,775,664,  against AOL  Inc., Google,  Inc.,  IAC 
Search  &  Media,  Inc.,  Gannett   Company,  Inc.,  and  Target   Corporation 
(collectively, "Defendants").

On November 6, 2012, the jury  unanimously returned a verdict as follows:  (i) 
I/P Engine had proven by a  preponderance of the evidence that the  Defendants 
infringed the asserted claims of both of the patents; and (ii) Defendants  had 
not proven by clear  and convincing evidence that  the asserted claims of  the 
patents are invalid  by anticipation.  The jury also  found certain  specific 
facts related to the ultimate question  of whether the patents are invalid  as 
obvious. Based on such  facts, on November 20,  2012, the U.S. District  Court 
issued a ruling that the patents-in-suit were not invalid as obvious, and  the 
clerk entered the Court's final judgment.

Google has filed three separate re-examinations of the asserted patents at the
USPTO, one request against the '420  patent and two requests against the  '664 
patent. Requests for re-examinations are a standard tactic used by  defendants 
in patent litigation cases.

The '420 Patent

On March  15, 2012,  Google submitted  a request  to the  USPTO for  ex  parte 
reexamination of U.S. Patent  No. 6,314,420, one  of the two  patents-in-suit. 
The request  was deposited  on March  16, 2012  and was  assigned Control  No. 
90/009,991. On July  18, 2012,  the USPTO  issued a  determination ordering  a 
reexamination. On September  25, 2012,  the USPTO issued  a first,  non-final 
office action where it adopted the rejections proposed by Google. Today,  the 
USPTO notified  I/P  Engine  that examiners  assigned  to  the  re-examination 
maintained their rejections of the claims of the '420 patent. I/P Engine will
continue to follow  the USPTO procedures  to uphold the  validity of the  '420 
patent, including  filing  an  appeal  to the  Board  of  Patent  Appeals  and 
Interferences of the USPTO.

The '664 Patent

On November 28, 2012,  Google submitted a  request to the  USPTO for ex  parte 
reexamination  of  U.S.   Patent  No.   6,775,664,  the  other   of  the   two 
patents-in-suit. The request was assigned  Control No. 90/012,722. On  January 
17, 2013, the USPTO issued a determination ordering a reexamination, but found
that three  of  the  prior  art  references  identified  by  Google  were  not 
considered prior art to the '664 patent.

In an  effort  to  have those  three  prior  art references  considered  in  a 
reexamination request  of U.S.  Patent No.  6,775,664, Google  filed a  second 
reexamination request of that  patent on February 8,  2013. On March 7,  2013, 
the USPTO issued a determination ordering  a reexamination based on the  three 
additional references. The reexamination was assigned Control No. 90/012,791.

I/P Engine expects that  the two reexaminations of  U.S. Patent No.  6,775,664 
may be merged  into a  single proceeding. Further  action from  the USPTO  is 
expected, including  either  a  Notice  of Intent  to  Issue  a  Reexamination 
Certificate affirming  the patentability  of  all subject  claims or  a  First 
Non-Final Office Action.
