From a purely legal perspective, the answer is straightforward: no. The fundamental tenets of patent law—novelty and non-obviousness—are irreconcilable with the existence of prior art in the public domain. The software's prior public availability categorically disqualifies it from patent protection. Any attempts to claim patentability on derivative works would require a demonstrably high level of inventive innovation, a very high bar to meet in the software industry.
No, you cannot patent software that is already publicly available. To be patentable, an invention must be novel and non-obvious. Software that's already publicly available, whether through open-source distribution, commercial release, or public disclosure, lacks novelty. This means it's already known to the public, thus failing a fundamental requirement for patent eligibility. A patent protects new inventions. Once an invention is publicly known, it enters the public domain, and the opportunity to secure patent protection is lost. Furthermore, even if some aspects of the existing software were modified or improved, these modifications would need to be sufficiently inventive to be patentable; minor changes are unlikely to meet the threshold. You may still be able to obtain copyright protection for the source code itself, but that is different from a patent and protects against unauthorized copying rather than providing an exclusive right to the underlying idea or functionality.
