McDutchie writes "With open-source related lawsuits on the rise, a market is developing for automated tools that detect the presence of open-source code within larger application development environments. Palamida Inc. stepped in with IP Amplifier 3.0, essentially a search tool and a database that consists of more than 38 million of the most commonly used open-source files. Something Google-inspired called CodeRank is claimed to match code against the database. Hmm... maybe someone should run it on this, or even this." Of course, some open source code is perfectly welcome in commercial software, even if that software's code is not itself open; it's no secret or surprise that Microsoft, for instance, has taken advantage in some products of BSD-licensed code.
