The AIA established a mechanism for “post grant” review of one class of business method patents — financial services business methods — by the PTO’s Patent Trial and Appeals Board. This “covered business method,” or CBM, review procedure gave inventors threatened with a lawsuit the ability to petition the PTO to review — and potentially rescind — these types of patents on the ground that they were vague, abstract or overly broad. But the AIA did not extend this retrospective post-grant review authority to the many other business method patents that are currently providing ammunition to patent trolls. That’s why the administration and reform advocates have called on Congress to expand the CBM review to allow parties to challenge a broader range of business method patents. In layman’s terms, expanding the CBM program would make it harder for patent trolls to litigate invalid business method patents; instead of going to court, a business could petition the PTO to review the patent being asserted and would obtain a preliminary determination of validity within six months for a fraction of the cost of litigation.
To date, the USPTO PTAB has granted 18 out of 23 applications for review. A grant is issued based on a determination by the expert board that at least one claim is likely to be invalid, so the bar is high. As Congress seeks to strike the right balance between preserving the rights of patent holders to enforce valid patents and making it harder to engage in abusive litigation based on asserting business methods patents of dubious value, it would do well to adopt a tailored expansion of CBM to enable the PTO to weed out more of these patents outside of litigation.
To be clear, expanding the CBM provision would not make it easier to challenge valid patents as some have alleged. Patents for “technological inventions” are specifically excluded, as they are under the existing CBM proceeding, and the standard for PTO Board review is high. None of the proposed reforms, including the expansion of CBM, would disadvantage valid patents or in any way limit the rights of patent holders to assert valid patents. What these reforms would do is make it a bit easier for small businesses and inventors to fight back when faced with suits based on business method patents that should not have been issued in the first place. Congress should heed the administration’s call by enacting legislation that includes a narrowly tailored expansion of the CBM review proceeding. It should also ensure that the PTO has the resources it needs to discharge that additional responsibility and to do all of its critical work. Reform legislation that includes a tailored expansion of the CBM proceeding would level the playing field for innovators and restore confidence in the patent system so it can continue to be the engine of innovation.
