Patent No. US12032941 (titled "Method And System For Updating Legacy Software") was filed by Updraft Llc on Jun 6, 2021.
’941 is related to the field of computer software, specifically the automated updating of legacy software. Many older software programs are written in outdated programming languages, making them difficult to maintain and optimize for modern hardware. The patent addresses the problem of efficiently converting these legacy systems into modern, maintainable code without manual recoding.
The underlying idea behind ’941 is to automatically analyze legacy code, identify its key functionalities or features , and then use this understanding to generate new code in a modern programming language. This involves data mining the legacy code to identify identifiers, grouping these identifiers based on their relationships, and then determining potential features based on these groupings.
The claims of ’941 focus on a method performed by a computing device. The method involves obtaining legacy operational code that includes multiple versions written in different programming languages. The code is divided into sections based on the programming languages, and then data mined to identify identifiers. Features are determined by grouping lines of code based on these identifiers, and a set of requirements is generated from these features. Finally, new operational code is created using a new programming language based on these requirements.
In practice, the invention involves a multi-stage process. First, the system analyzes the legacy code to identify identifiers, which are names for variables, functions, and other code elements. These identifiers are then grouped based on various relationships, such as their proximity in the code, their semantic similarity, or their association with specific data. These identifier groups are then used to infer potential features of the code, such as specific functionalities or business rules.
The invention differentiates itself from prior approaches by automating the process of understanding and converting legacy code. Instead of relying on manual analysis or simple translation, the system uses data mining and feature extraction techniques to identify the core functionalities of the legacy code. This allows for a more accurate and efficient conversion to a modern programming language, while also eliminating the need for emulators or converters to run the old code.
In the late 2010s when ’941 was filed, at a time when software updates were typically implemented using monolithic deployments, systems commonly relied on manual code analysis and refactoring rather than automated feature extraction, and when hardware or software constraints made cross-language interoperability non-trivial.
The examiner allowed the claims because the prior art failed to disclose or suggest determining that the plurality of versions of the legacy operational code includes more than one legacy programming language; dividing the legacy operational code into a plurality of sections based on different legacy programming languages; data mining the plurality of sections of the legacy operational code to determine a plurality of identifiers; and determining a plurality of features of the plurality of sections of the legacy operational code based on grouping lines of code of the plurality of versions based on the plurality of identifiers.
This patent contains 10 claims, with independent claims 1 and 6. Independent claim 1 focuses on a method for converting legacy operational code into new operational code, while independent claim 6 focuses on a computing device configured to perform the same conversion. The dependent claims generally elaborate on and refine the steps and features described in the independent claims.
