NORTHERN DISTRICT OF CALIFORNIA 

SAN FRANCISCO DIVISION 

LOOKSMART GROUP, INC., 

 Plaintiff, 

vs. 

MICROSOFT CORPORATION, 

 Defendant. 

Case No. 3:17-cv-4709-JST 

STIPULATION AND [PROPOSED] 

ORDER GRANTING THE PARTIES’ 

REQUEST TO AMEND CONTENTIONS 

PURSUANT TO PATENT L.R. 3-6 

DEMAND FOR JURY TRIAL 

 Pursuant to Local Rules 7-1(a)(5) and 7-12, and Patent Local Rule 3-6, Plaintiff 

Looksmart Group, Inc. (“Looksmart”) and Defendant Microsoft Corporation (“Microsoft”) 

hereby agree and stipulate as follows: 

 WHEREAS, LookSmart served its Patent L.R. 3-1 Infringement Contentions on February 

14, 2018 and Microsoft served its Patent L.R. 3-3 Invalidity Contentions on April 2, 2018 

pursuant to the Court’s Scheduling Order (ECF No. 45); 

 WHEREAS, on May 4, 2018, LookSmart notified Microsoft of its intent to seek the 

Court’s leave to amend its Infringement Contentions and concurrently provided Microsoft with a 

copy of its proposed Amended Infringement Contentions and a draft motion for leave to amend;

 WHEREAS, Microsoft does not oppose LookSmart’s request to amend its Infringement 

Contentions in the manner represented in LookSmart’s May 4, 2018 correspondence, and 

LookSmart does not oppose Microsoft’s request to amend its Invalidity Contentions so long as 

Microsoft does so on or before June 1, 2018 and its amendments are commensurate in scope with 

LookSmart’s amendments; 

 WHEREAS, LookSmart respectfully submits that good cause exists to amend its 

Infringement Contentions pursuant to Patent L.R. 3-6 because: 

(a) LookSmart’s amended contentions rely on information ascertained from Microsoft’s 

non-public, confidential and proprietary information, which was not known to 

Looksmart prior to Microsoft’s production, and LookSmart diligently reviewed such 

information; 

(b) LookSmart’s proposed amendments will not unduly prejudice Microsoft due to the 

relatively early stage of the case and because they do not assert any new patent 

claims; 

(c) LookSmart acted diligently in seeking this amendment since none of these above 

bases for amendment were previously available to LookSmart outside the confidential 

discovery and disclosure mechanisms of this case; 

(d) LookSmart agrees that in its original theory, it found no evidence that a “dynamic 

rank” value was stored in the “merged indices” for the Accused Products, though it 

has requested additional information to determine whether a different rank value (e.g., 

“sort rank”) is; 

(e) However, LookSmart contends in its amended infringement contentions that the 

“dynamic rank” value is stored in a “query cache” used with the accused product, and 

that this is LookSmart’s primary infringement theory subject to its remaining 

questions on the rank values stored in the “merged indices.” 

 WHEREAS, Microsoft respectfully submits that good cause exists to amend its Invalidity 

Contentions pursuant to Patent L.R. 3-6 because:

(a) Microsoft contends that the change in the infringement theories between LookSmart’s 

initial Patent L.R. infringement charts and its amended “query caching” theory 

present LookSmart’s application of certain claim terms in a new light, which 

Microsoft did not appreciate when Microsoft prepared its responsive Patent L.R. 3-3 

invalidity contentions; 

(b) In view of LookSmart’s amended infringement contentions, Microsoft is performing 

an additional search for prior art to address these changes provided on May 4, 2018; 

(c) Microsoft’s responsive charts will be diligently served less than 30 days after 

Looksmart first provided its proposed its amended Patent L.R. infringement charts; 

(d) Looksmart will not be unduly prejudiced by supplementation of Microsoft’s Patent 

L.R. invalidity contentions because it is relatively early in the case, and the existing 

Patent L.R.’s already reflect a response to defend against a claim of infringement. 

WHEREAS, LookSmart and Microsoft have agreed that, to avoid burdening the Court, 

the parties will stipulate to allow amendments to their respective Infringement and Invalidity 

Contentions, subject to the Court’s approval. 

IT IS HEREBY STIPULATED AND AGREED, by and between LookSmart and 

Microsoft, subject to the Court’s approval, that: 

(a) LookSmart is hereby given leave to amend its Patent L.R. 3-1 infringement 

contentions in the manner set forth in LookSmart’s May 4, 2018 correspondence; and 

(b) Microsoft is hereby given leave to amend its Patent L.R. 3-3 invalidity contentions on 

or before June 1, 2018 in a manner that is commensurate in scope with LookSmart’s 

amendments.
