`
`In Re: PersonalWeb Technologies, Inc., et al., Patent Litigation (Case No:
`5:18-md-02834-BLF); Personal Web Technologies - Heroku, Inc. (5-18-cv-
`00162-BLF)
`
`Dear Mr. Lee and Mr. Berta:
`
`At the Preliminary CMC on September 20, 2018, Mr. Berta told the Court that Heroku is
`considering filing a “Rule 11 Motion to Dismiss” based on the allegation, “[T]here’s literally not one
`fact that’s pleaded in [PersonalWeb’s complaint against Heroku].”
`
`As an initial matter, PersonalWeb’s complaint against Heroku meets and exceeds the pleading
`requirements of the Federal Rules as well as the requirements set forth by Iqbal/Twombly.
`Furthermore, PersonalWeb’s complaint against Heroku does recite specific facts regarding the
`manner in which its infringing website operates. The complaint contains facts alleging each of the
`elements of at least one claim in each of the four asserted patents in suit. While not required to defeat
`a Rule 12 motion (or satisfy Rule 11 requirements), the operative complaint does not include specific
`examples of index files (“webpage base files” in the proposed amended complaint), asset files, and
`fingerprints in URI’s involved in the described infringing activities.
`
`Nonetheless, in an effort to resolve this issue, and avoid unnecessary motion practice, this
`letter provides Heroku with specific examples of webpage base files, asset files, and fingerprints in
`URI’s involved in Heroku’s infringing activity, some of which will be included in the Second
`Amended Complaint that PersonalWeb will be filing against Heroku. We ask that Heroku correct us
`if it believes we have any of these facts incorrect. As we have referenced in open court, there have
`been some Website Operators who were sued and PersonalWeb subsequently dismissed based on
`information they provided us. We are always willing to hear what Website Operators have to say,
`particularly if that defendant disagrees with facts alleged.

`
`Accordingto the archivesat archive.org, by way of example: On December25, 2013, Heroku
`served a webpagebase file substantially similar to the attached file': Heroku_2013_base_file.html.
`This file was served by host server “heroku.com”. When this file was served to archive.org on
`December 25, 2013, according to the headers archived by archive.org, it was served with an “etag”
`header with the value ‘"22f26b42b31065d3a9c4882c440129b6"’. Our understanding is that this
`ETag was a content-based identifier of the webpage base file served by heroku.com.
`
`This December 25, 2013 heroku.com webpagebasefile expressly included referencesto the
`assetfiles listed below. Accordingto the archives at archive.org: Each of theseasset files was served
`to archive.org on or about December 25, 2013. Copies of these asset files as they are archived by
`archive.org have been downloaded, some of which were modified by ourlitigation software
`programming referenced in footnote one and are attached. Each oftheseasset files was served by
`the host server at “d4yt8x19b7in.cloudfront.net”, with an “etag” header with the ETag value listed
`below for the correspondingasset file and with a “server type” header with the value “AmazonS3”.
`For eachlisted asset file, the value of the “etag” header served with thatassetfile is the MD5 hash of
`the contents of that assetfile.
`
`Accordingto the archives at archive.org: This December 25, 2013 heroku.com webpage base
`file included references to the asset files “placeholders-de90ef0087cad3ae8e589a403 | 2e4f8d.js” and
`“retina-6aaf485d185c125a62bd793d2c6ad419.js”. Each ofthese asset files was served to archive.org
`on or about December 25, 2013. Copiesof theseasset files as they are archived by archive.org have
`been downloaded, modified by ourlitigation software programming referenced in footnote one, and
`are attached. Both oftheseassetfiles were served by the host serverat “d4yt8x19b7in.cloudfront.net”.
`Both of these asset files were served with a “server type” header with the value “AmazonS3”. The
`MDShash valueof the assetfile “placeholdersde90ef0087cad3ae8e589a403 12e4f8d.js” prepended
`with the seed string “2.2.2production-1.0” is “de90ef0087cad3ae8e589a403 12e4f8d”. The MD5
`hashvalueofthe assetfile “retina-6aaf485d185c125a62bd793d2c6ad419 js” prepended with the seed
`string “2.2.2production-1.0” is “6aaf485d185c125a62bd793d2c6ad419”.
`
`Accordingto the archives at archive.org: On December 24, 2014, Heroku served a webpage
`base file substantially similar to the attached file (see footnote one): Heroku_2014_base_file.html.
`This file was served by host server “heroku.com”. When this file was served to archive.org on
`December24, 2014, accordingto the archives at archive.org, it was served with an “etag” header with
`the value ‘W/"6c23585e273cd3c7da0a2 1ed28f942f2"’. This file was also served with a “server type”
`header of “Cowboy”. Our understanding is that this ETag served was a content-based identifier of
`the webpagebasefile served by heroku.com.
`
`
`
`' By “substantially similar” we are referring to the fact that Archive.org — while a recording/preservation service —
`modifies the webpagebasefile in order to re-create the experience of visiting the webpageat the archivedtime that
`most often appear insignificant to someone with a generalinterest in seeing what a website lookedlike at some point in
`the past. Our specially written litigation software programming has removed as manyofthese modificationsas can be
`determined from the modified file.

`
`This December 24, 2014 heroku.com webpage basefile expressly included references to the
`assetfiles listed below. According to the archives at archive.org: Each ofthese asset files was served
`to archive.org on or about December 24, 2014. Copies of these file files as they are archived by
`archive.org have been downloaded, some modified by our litigation software programming
`referencediin footnote one and are attached. The asset files “screenshot-macys.png”, “screenshot-
`scoot.png”, and “screenshot-lutron.png” listed below were served by the host server at heroku.com,
`with a “server type” header having the value “Cowboy”. Eachofthe remainingassetfiles listed below
`wasserved by the host server at “d4yt8x19b7in.cloudfront.net” and a “server type” header with the
`value “AmazonS3”.
`Each of the listed asset
`files, whether served from “heroku.com” or
`“d4yt8x19b7in.cloudfront.net”, was served with an “etag” header having the ETagvalue listed below
`for the correspondingassetfile. For each listed assetfiles, the value of the “etag” header served with
`that asset file is the MDS hashofthe contents ofthat assetfile.
`
`These aforementioned examples demonstrate PersonalWeb's evidentiary support for the
`factual contentions alleged against Heroku in PersonalWeb's operative complaint, which will be
`furtherilluminated in the Second Amended Complaint. These examples support infringement of each
`of the four claimsfor relief asserted against Heroku.
`
`Again, we welcome comments, questions or disagreements.
