In the run-up to Oil States, a frequent criticism by opponents of patent reform was that the PTABPatent Trial and Appeal Board. Reviews adverse decisions of examiners on written appeals of applicants and appeals of reexaminations, and conducts inter partes reviews and post-grant reviews. The Board also continues to decide patent interferences, as it was known as the Board of Patent Appeals and Interferences (BPAI) before the AIA. was “unfair” and that it invalidated patents at a rate far higher than the district courts would if they had the chance.
Unfortunately this is contradicted by the actual facts, which is something we’ve seen before from opponents of patent reform. (See, e.g., the Chamber of Commerce rankings, the Alice ‘storm’, and misleading testimony to Congress regarding conflicts between PTABPatent Trial and Appeal Board. Reviews adverse decisions of examiners on written appeals of applicants and appeals of reexaminations, and conducts inter partes reviews and post-grant reviews.

The truth is that the PTABPatent Trial and Appeal Board. Reviews adverse decisions of examiners on written appeals of applicants and appeals of reexaminations, and conducts inter partes reviews and post-grant reviews. The Board also continues to decide patent interferences, as it was known as the Board of Patent Appeals and Interferences (BPAI) before the AIA., when faced with a patent, has outcomes roughly similar to comparable procedures both in the U.S. and overseas—when they make a decision, they find that a little more than forty percent of patents are invalid.

EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership. Oppositions and Nullity Proceedings
In Europe, rather than inter partes review and district court litigation on validity, there are opposition proceedings at the European Patent Office (EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership.) and nullity proceedings in European national courts.
Oppositions
Oppositions are the most similar[1. Though certainly not identical. For example, EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership. oppositions can be based on subject-matter eligibility challenges, a ground that is not available in IPRIntellectual Property Rights. Usually associated with formal legal rights such as patent, trademark, and copyright. Intellectual property is a broader term that encompasses knowledge, information, and data considered proprietary whether or not it is formally protected..] European procedure to U.S. post-grant proceedings like IPRIntellectual Property Rights. Usually associated with formal legal rights such as patent, trademark, and copyright. Intellectual property is a broader term that encompasses knowledge, information, and data considered proprietary whether or not it is formally protected.. So it’s instructive to examine how many European patents are opposed and the outcomes of those oppositions.
Fortunately, the EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership. makes available detailed statistics on exactly these questions. Approximately 4% of European patents are opposed, and of those, approximately 32% of oppositions are not instituted.[2. For the sake of coherent terminology throughout, I’ve used U.S. equivalent terms—a proceeding with a threshold requirement is either instituted or not instituted at the threshold, rather than using the European terms such as rejecting an opposition.] 27% of oppositions result in a final decision invalidating all claims of the patent, while the remaining 40% of patents are modified in some form and maintained as patents.[3. These statistics vary slightly year-to-year, but the roughly 30/30/40 split is consistent.] (EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership. opposition statistics appear to omit patents where the parties settled mid-proceeding.) Each year, the EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership. handles approximately 4,000 oppositions, meaning that approximately 1,100 European patents are invalidated in their entirety on a yearly basis.[4. For comparison, the PTABPatent Trial and Appeal Board. Reviews adverse decisions of examiners on written appeals of applicants and appeals of reexaminations, and conducts inter partes reviews and post-grant reviews. The Board also continues to decide patent interferences, as it was known as the Board of Patent Appeals and Interferences (BPAI) before the AIA. receives approximately 1,500 petitions per year, some of which are directed to the same patent and a number of which are never instituted. The EPOEuropean Patent Office, which is the operating arm of the European Patent Organisation (also EPO), which is an independent treaty organisation that is not part of the European Union, although there is a substantial overlap in membership. opposition procedure invalidates significantly more patents on a yearly basis than IPRIntellectual Property Rights. Usually associated with formal legal rights such as patent, trademark, and copyright. Intellectual property is a broader term that encompasses knowledge, information, and data considered proprietary whether or not it is formally protected. does.]
Nullity
Currently, nullity proceedings occur in national courts (most frequently the German courts). These somewhat resemble an invalidity claim in a U.S. court, though with significant differences regarding court procedures and the composition of the relevant judicial body. Data on European court proceedings can be difficult to obtain; as a result, it can be difficult to estimate outcome rates for nullity actions. One study, examining German nullity data,[5. German data is particularly significant as the German court system is likely the most frequently used European court system for patent disputes.] found that—excluding cases that settled or were otherwise withdrawn—24% of challenged patents were entirely valid, 37% were partly valid and partly invalid, and 39% were completely invalid.
While inexact because of these two separate systems, a split of 33%/33%/33% is a good rule of thumb for outcomes in European patent challenges. One third of the time the patent is entirely valid, one third of the time it’s entirely invalid, and one third of the time you get a mixed result.
U.S. District Courts
While Oil States has made clear that neither an Article III judge nor a jury is required when invalidating a U.S. patent, district court judges still decide validity issues on a regular basis. The most comprehensive study of outcomes I am aware of, authored by Professors John Allison, Mark Lemley, and David Schwartz, examined every merits decision on every patent case filed in the years 2008 and 2009. This data set included decisions at all stages, from summary judgment to jury decisions. And the result?
When a patent is challenged as invalid, district courts agree that it was in fact invalid 42.6% of the time.
So when courts in the U.S. look at patents, just like European courts, it appears that a little more than 40% of the time, the court finds the patent should not have been granted.[6. This does include district court judgments of invalidity based on § 101 and § 112, which are not available to PTABPatent Trial and Appeal Board.

After removing these categories, we receive a better picture of the PTAB’s actions.
There are 2,016 final decisions, 123 dismissals, and 2,000 denials of institution. That’s 4,139 total decisions.
Of those, 2,000 found the patent valid at the first hurdle of institution. Another 123 dismissed the proceeding without affecting the patent. And, of the final decisions, another 389 found all claims patentableEligible to be patented. To be patent-eligible, an invention must fall into the categories listed in 35 U.S.C. § 101 (i.e., process, machine, manufacture, or composition of matter) and cannot be an abstract idea or a law of nature..

[9. Even if every single joined petition had been joined to one of the 39% of decisions that affected at least one challenged claim—an unlikely circumstance, compared to the likelihood that they are more evenly distributed across decisions—the numbers shift only slightly, becoming 55% and 45%.]
Petition vs. Patent
These numbers are on a petition-by-petition basis, not a patent-by-patent basis. Since only one petition needs to invalidate a claim for the claim to be invalidated entirely, the patent-by-patent numbers will generally be higher than petition-by-petition; the PTAB’s own statistics illustrate this phenomenon. However, a patent may require more than one petition in order to find all claims invalid (most famously in the case of a single patent with 306 claims).

The Board also continues to decide patent interferences, as it was known as the Board of Patent Appeals and Interferences (BPAI) before the AIA. statistics show that on a per-patent basis, 58% of patents are unchanged, 6% of patents have a request for adverse judgment, 7% of patents have some claims found unpatentable, and 29% of patents have all challenged claims found unpatentable (compared to 66.5%, 4.5%, 5%, and 24% on a per-petition basis). From this, combined with the PTAB’s estimate that per-patent institution rates are around 6% higher than per-petition institution rates, a fair estimate is that of the 58% of unchanged patents, around 25% are due to denials of institution and another 7.5% are due to final written decisions upholding the patent entirely, with the remaining 25.5% due primarily to settlements.[10. This is consistent with the rough breakdown on a per-petition basis, which is unsurprising given that the vast majority of patents only face one or two petitions.]

This is also consistent with one possible worst-case boundary estimate. Around 79% of petitions are filed either as single petitions or on nearly the same day (meaning that they generally will cover different claims from one another). If we assume that none of the 21% of potentially duplicative petitions are joined, and are all denied institution—an unrealistic worst possible case assumption—the adjusted patent-by-patent invalidity estimate would become 1,627 at least partially invalid patents out of 3,269 adjudicated patents; in other words, a reasonable worst-case bound for the rate at which decisions made by the PTABPatent Trial and Appeal Board.
