Semmle Assigned Three Patents

Content-addressable data storage
Semmle Limited, Oxford, Great Britain, has been assigned a patent (9,830,345) developed by Baars, Arthur, Oxford, Great Britain, for a “content-addressable data storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods, systems, and apparatus, including computer programs encoded on computer storage media, for storing data in a version control system. One of the methods includes maintaining, in a data store, a tree-structured index of files in which each leaf node stores an entry for each file in a plurality of files for a snapshot that includes a unique file identifier for the respective file, receiving a request for a particular file, generating a hash of a particular file path for the particular file, identifying, using the hash of the particular file path, a leaf node in the tree-structured index that includes an entry for the particular file, identifying, in the leaf node, an entry for the particular file path, obtaining, from the entry, the unique file identifier for the particular file in the data store, and using the unique file identifier for the particular file in response to the request.”

The patent application was filed on September 26, 2016 (15/275,681)

Snapshot manifest for static analysis results
Semmle Limited, Oxford, Great Britain, has been assigned a patent (9,830,335) developed by Tibble, Julian, Oxford, Great Britain, for a “snapshot manifest for static analysis results.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using a snapshot manifest when storing files in a data store. One of the methods includes computing first static analysis results for a current snapshot, requesting, from a data storage system, a manifest that includes a plurality of unique identifiers that each identify a corresponding second object of second static analysis results for a previous snapshot, determining, for each first object of the first static analysis results, a unique identifier for the first object, determining, for each first object of the first static analysis results, whether the unique identifier for the first object occurs in the manifest, generating a batch of first objects having unique identifiers that do not occur in the manifest, and providing, to the data storage system, the batch of first objects having unique identifiers that do not occur in the manifest.”

The patent application was filed on February 17, 2017 (15/435,672).

Providing user-specific source code alert information
Semmle Limited, Oxford, Great Britain, has been assigned a patent (9,830,148) developed by Mo, Man Yue, Oxford, Great Britain, for a “providing user-specific source code alert information.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing user-specific source code alert information. One of the methods includes receiving a user identifier of a user that has previously accessed source code of a code base, and receiving source code access data that includes access metrics related to prior user access of the source code. Based on the source code access data and on source code that has previously been accessed by the user, relevant source code that has previously been accessed by other users is determined. Source code alerts are received for the code base, and a user-specific organization of alerts is provided for the user that identifies alerts for source code problems occurring in the source code, including at least one source code unit that has previously been accessed by another user.”
