LITIGATION WITH AOL, GOOGLE ET AL.

Motions for Supplemental Damages and Ongoing Royalties Remain Pending in U.S.
                                District Court

NEW YORK - April 4, 2013 - Vringo, Inc. (NYSE MKT: VRNG), a company engaged in
the innovation,  development  and  monetization  of  mobile  technologies  and 
intellectual property, today  announced that its  wholly-owned subsidiary  I/P 
Engine, Inc. has filed a notice of appeal in its litigation against AOL, Inc.,
Google, Inc., IAC  Search &  Media, Inc.,  Gannett Company,  Inc., and  Target 
Corporation (collectively,  "Defendants").  I/P  Engine's  notice  of  appeal 
applies to  matters related  to  laches and  the  jury's calculation  of  past 

I/P Engine has engaged Joseph  R. Re, Esq., a partner  at the law firm  Knobbe 
Martens Olson &  Bear LLP,  as counsel for  proceedings at  the United  States 
Court of Appeals for  the Federal Circuit.  Attorneys from Dickstein  Shapiro 
LLP, trial counsel to I/P Engine, remain engaged.


On November  6, 2012,  a jury  in  United States  District Court  in  Norfolk, 
Virginia ruled in favor of I/P  Engine and against Defendants with respect  to 
Defendants' infringement of the asserted claims of U.S. Patent Nos.  6,314,420 
and 6,775,664.  After  upholding the  validity  of the  patents-in-suit,  and 
determining that the asserted claims of the asserted patents were infringed by
Defendants, the jury found that reasonable royalty damages should be based  on 
a "running royalty," and  that the running royalty  rate should be 3.5%.  I/P 
Engine presented evidence at trial that  the appropriate way to determine  the 
incremental  royalty  base  attributable  to  Google's  infringement  was   to 
calculate 20.9% of Google's  U.S. AdWords revenue, then  apply a 3.5%  running 
royalty rate  to that  base. The  jury also  awarded I/P  Engine a  total  of 
approximately $30.5 million as past damages. On November 20, 2012, the  clerk 
entered judgment  on  the verdict.  On  April  3, 2013,  the  District  Court 
resolved all of the pending motions for judgment as a matter of law and for  a 
new trial  on damages.  Certain matters  remain pending  before the  District 
Court, as described below.

Notice of Appeal

I/P Engine has filed a Notice of Appeal, appealing to the United States  Court 
of Appeals for the Federal Circuit the final judgment entered by the  District 
Court on April 3, 2013. I/P Engine is appealing the District Court's November
20, 2012 ruling that the doctrine of laches barred I/P Engine from  recovering 
damages for any  infringements by  Defendants occurring  before September  15, 
2011, the date on which I/P Engine  filed suit. I/P Engine is also  appealing 
the District Court's April  3, 2013 ruling denying  I/P Engine's Motion for  a 
New Trial on the Dollar Amount of Past Damages.

Ongoing Activity in U.S. District Court

On November 9, 2012, I/P  Engine filed a Motion  for an Award of  Pre-Judgment 
Interest, Post-Judgment Interest  and Supplemental Damages.  This motion  has 
been fully briefed and is ripe for judicial determination.

On December 18, 2012, I/P Engine filed a Motion for an Award of  Post-Judgment 
Royalties. On April 3, 2013, the District Court ordered Defendants to respond
within fifteen (15) days. I/P Engine will  then be permitted to file a  reply 
to Defendants' response within seven (7) days, at which point, the motion will
be ripe for judicial determination.

In this  motion,  I/P Engine  has  requested  that the  District  Court  order 
Defendants to pay ongoing running royalties for their continuing  infringement 
of I/P Engine's  patents from  November 20,  2012, the  date of  the entry  of 
judgment on the verdict, until either (i) Defendants cease their  infringement 
or (ii) April 4, 2016, the expiration date of the patents.

I/P Engine argued that the Court should conclude that an upward adjustment to
a 5% running royalty rate for Defendants' ongoing post-judgment infringement
is appropriate. I/P Engine's damages expert, Dr. Stephen Becker, also reached
the conclusion that there is no reason to depart downward from the 5% royalty
rate because the patents are known to be valid and the patented technology is
acknowledged to be "mission critical" for Google.

Further,  I/P  Engine   argued  that  Defendants'   ongoing  infringement   is 
undisputedly willful  because Defendants  are fully  aware that  their use  of 
AdWords has been adjudged to infringe all of the asserted claims of the  valid 
and enforceable  patents-in-suit. Therefore,  I/P Engine  requested that  the 
District Court enhance the ongoing royalty rate to 7% in light of  Defendants' 
ongoing willful infringement.

Finally, I/P Engine requested that the District Court order that, among  other 
things, Defendants pay ongoing royalties to I/P Engine on a quarterly basis in
certified funds or by  wire transfer, accompanied  by a statement  certifying, 
under penalty of perjury, the U.S. revenue attributable to Defendants' use  of 
AdWords and the calculation of the royalty amount.
