President Obama has now signed into law the America Invents Act (AIA) – the largest reform of U.S. patent law in over half a century. The legislation was passed by wide margins in both the House of Representatives and the Senate, reflecting the very broad bi-partisan support for long overdue reforms. The reforms can be characterized in four major groupings:

  1. “First-to-file” replaces “First-to-invent”
  2. Improving patent quality: Making corrections and getting rid of bad patents
  3. Improving fairness: Ending abusive practices
  4. Changes to the United States Patent and Trademark Office (USPTO) fees and funding, including a 15% surcharge

The AIA also contains a number of other miscellaneous provisions, which are listed at the end of this article.

1. “First-to-file” replaces “First-to-invent”

The United States is the last industrial country to adopt a first-to-file system (Canada did so on October 1, 1989). In a first-to-file system, the first inventor to submit an application for an invention to the patent office has the right to claim that invention. Subsequent applicants, even though they may have invented the same invention slightly earlier, are too late. Under the former “first-to-invent” system there was an uncertain, expensive, and time consuming process (known as Interference Proceedings) to determine which competing application owned by different applicants was entitled to a patent. The first-to-file system eliminates this process and replaces it with public notice of an inventor’s priority filing date and serial number: easily verified, objective, public information printed on the face of the document.

The law retains a one-year grace period for an inventor’s public disclosure prior to the first filing, so that an inventor’s own disclosures in the grace period will not be prior art that will prevent a patent from issuing. A new term, “effective filing date,” is introduced, meaning the date on which the inventor filed an application for the invention in the U.S. or elsewhere. A peculiar feature of the new U.S. law is that independent disclosure by third parties in the one-year grace period after the inventor’s own disclosure but before the effective filing date, will not prevent the inventor from obtaining a patent. In Canada, independent disclosure of the same invention by an unrelated third party any time before the claim date would end the inventor’s opportunity to file.

Under previous U.S. law, “public use, sale or an offer for sale” and making the invention “known or used by others” were only relevant to patentability, or as a basis for establishing prior invention, if the activity occurred in the U.S. Under the new law, other than the inventor’s own disclosures, patenting, description in a printed publication, public use, putting on sale, or otherwise making the claimed invention available to the public before the effective filing date anywhere in the world will bar the grant of a patent. Formerly, a public use, sale or offer for sale, outside the U.S. (e.g., in Canada) more than a year before filing might not have prevented an applicant from seeking a U.S. Patent.

For all applicants, American or otherwise, the grace period under the AIA and the one-year international priority period permitted under U.S. law or treaty, are additive. By contrast, in Canada, an inventor is entitled to either the one-year grace period or the one-year international priority period whichever expires first. That is, a U.S. (or other) applicant who has publicly disclosed the invention anywhere, must file in Canada within one year of that disclosure in all circumstances. There is no additional year permitted based on a first filing, such as a U.S. provisional application. In the great majority of countries there is no grace period: any public disclosure before filing counts as prior art.

To combat feared misappropriation of inventions in the grace year, the newly-named Patent Trial and Appeal Board (formerly the Board of Patent Appeals and Interferences) has the duty to determine who disclosed what to whom first in “derivation proceedings.”

In summary, the date of first disclosure – a date prior to the effective filing date – may determine both entitlement to apply for patents, and applicability of prior art, in some ways similar to the former importance of inventorship and date of invention. It is unclear whether disputes over “first-to-disclose” may then yield similar evidentiary problems to those of the former “interference proceedings.” These first to file provisions will come into effect on March 16, 2013.

2. Improving patent quality: Making corrections and getting rid of bad patents

The AIA includes many changes directed toward improving the quality of patents and toward permitting third parties to challenge the validity of their competitors’ claims much more quickly and easily, with the benefit of the better technical expertise of the USPTO (as opposed to non-specialist courts) at considerably less expense than through litigation.

(a) Right to expedite examination, and to obtain supplemental examination

The law also provides a new mechanism for prioritized examination at the request of the applicant. Further, in addition to existing examination procedures, there will be new opportunities for patent owners to have corrections made in their patents through supplemental examination if new information comes to light. A patent owner will continue also to have the same opportunities as before to seek re-examination or re-issue of a patent.

(b) Third party right to submit and explain relevant prior art

The AIA includes significantly improved ways for third parties to submit relevant information to the USPTO during prosecution of a competitor’s applications, or to submit that information after the competitor’s patent has issued. In either case the third party may now explain how the additional information pertains to the claims. The Director of the USPTO may institute re-examination of any patent if the Director considers that there is a “substantial new question of patentability” raised.

(c) New ways for challenging patent claims after grant

The formerly problematic Inter Partes Re-examination (i.e., re-examination where both the patent owner and a third party challenger had opportunities to make written submissions, and even then only on the basis of patents and other printed publications) is replaced by two new procedures.

First, Post Grant Review, may be initiated by any third party and is applicable within nine months of grant. It permits a challenge to issued claims on a wide variety of bases. Second, Inter Partes Review may be initiated by any third party after the expiry of the period for Post Grant Review. Inter Partes Review may only be requested on the basis of patents, printed publications, and submissions of the patent owner before the USPTO or Federal Court.

In either case respective higher threshold standards will apply: that it is more likely than not that at least one challenged claim is unpatentable or that there is a reasonable likelihood that the petitioner would prevail. There is no presumption of validity. The burden of proof is the preponderance of evidence. There are to be rights of reply, right to an oral hearing, rights to stays of co-pending civil litigation, and rights of appeal to all parties. Both procedures are subject to explicit, short time limitations to yield an outcome within, at most, eighteen months.

Many of these changes greatly improve a third party’s opportunity to participate and to make sure that its arguments are fully and properly considered. The ability of a third party to obtain a stay of civil proceedings by a non-specialist court while the issues are being considered by a body of specialist technical expertise (i.e., the USPTO) is new and important. The ability of the third party to appeal the decision also overcomes one of the major disincentives of the old Inter Partes eexamination procedure.

(d) Other Provisions

Finally, the AIA includes a controversial provision that would deem tax planning strategies to be obvious, and authorizes continuation of a pilot programme that reviews the patentability of the claims of business method patents.

3. Improving in fairness: Ending abusive practices

(a) Filing by non-inventors facilitated

The AIA permits greater scope for patent owners to proceed with the filing and prosecution of patent applications where an inventor under an obligation to assign is either unavailable or unwilling to co-operate. The AIA facilitates the filing of applications based on groups of inventors, and provides better protection to their owners from having different parts of their own work cited against them as prior art.

(b) “Micro entity” filings

A definition of “micro entity” has been introduced to permit an even greater reduction in fees than “small entities”. The definition is very complicated, and may hold great potential to give rise to an allegation that the status was improperly claimed. A similar provision in Canadian law proved problematic, and eventually required legislative amendment.

(c) Elimination of abused technical grounds for unenforceability

Many old, much-abused grounds for holding claims unenforceable were removed. These include the requirement for a description of the best mode of practicing the invention (still required for grant, but no longer a ground of unenforceability); the requirement for an independent opinion to avoid claims for punitive damages; and several sections pertaining to intention that were formerly used for dubious, vexatious, and frequently meritless allegations of inequitable conduct.

(d) Marking made easier and safer

The current law was amended to permit virtual patent marking to be implemented on the Internet, and also to end abusive and opportunistic third party enforcement of the false marking provisions.

(e) New prior user defence

A new prior user defence, particular to prior use by the defendant, is provided. It requires the defendant to show that it carried out the activity of which the patent owner complains more than one year prior to the effective claim date, whether that activity was made public or not. This defence already exists in other countries.

(f) Curtailment of litigation conduct

New provisions have been added to prohibit poorly pleaded, general allegations against a multitude of defendants in a single action. A related provision requires the naming of all plaintiffs having an actual interest in litigation. The object is to discourage the filing of infringement actions against a host of defendants in a manner designed perhaps less to vindicate patent rights than to extract settlements from defendants. An example is those in the pharmaceutical and communications industries, who might prefer the certainty of settlement to the costs and risks of patent litigation, without regard to substantive merit.

4. Changes to USPTO fees and funding: 15% Surcharge

The USPTO generates a surplus in fees, that surplus being diverted to Congress. At the same time the USPTO has the largest backload of work in its history. The USPTO has long requested more funds to hire and train examiners, and thereby to raise quality and reduce delay times. There were strong, though ultimately unsuccessful, efforts to end fee diversion entirely.

Instead the USPTO is being allowed to charge a “temporary” 15% fee charge on almost all standard fees, and the Director is being given the power to adjust fees. The 15% surcharge will become effective on September 26, 2011.

The America Invents Act may not be the end of the USPTO fee diversion issue.

Miscellaneous Provisions

(a) Creation of four satellite offices. The first USPTO regional office is to be in Detroit.

(b) Statutory Invention Registration has been repealed. The provision was little used, and was largely obsolete in view of routine publication of applications.

(c) Establishment of a “Patent Ombudsman Program” for small business concerns.

(d) Establishment of studies related to various patent issues.

(e) An amendment to prohibit the patenting of claims directed to or encompassing a human organism.
