Patents protect inventions.  However, patents protect only certain inventions.  In order to be patentable, an invention must fall within one of four categories of patent-eligible subject matter: articles of manufacture, machines, processes, and compositions of matter. 35 U.S.C. §101.  There are some things that are not patentable (i.e. are patent-ineligible subject matter): laws of nature, natural phenomena, and abstract ideas.

In 2014, in Alice Corp. Pty. Ltd. v. CLS Bank International, 573 U.S. 208, 216, 219 (2014), the Supreme Court established a two-part test to determine whether an invention is patent-eligible.  In the first step, a determination is made as to whether the claimed invention falls within one of the categories of patent-ineligible subject matter.  If it does, the second step is performed:  a determination of whether the claimed invention has an inventive concept that transforms the patent-ineligible subject matter into something patentable.

Quick answer: no!

The Federal Circuit Court of Appeals recently tangled with a patent application for an invention that did not have scientific support.  The court affirmed a decision of the Patent Trial and Appeal Board rejecting a patent application on these grounds.  While this is not a common occurrence, in this case, it’s an easy conclusion to reach.

In In re Huping Hu, 2021 U.S. App. LEXIS 7776, the inventors applied for patents for inventions related to “quantum entanglement.”  According to the inventors, quantum entanglement is “quantum spins of photons, electrons and nuclei.”  The inventors explained that “quantum spins of photons, electrons and nuclei have now been successfully entangled in various ways for purposes of quantum computation and communication.”  The inventors said that quantum entanglement is a phenomenon that happens if particles, such as photons and electrons, become linked, and, when separated, the mechanical states of the molecules are still linked such that if the state of one particle is changed, the linked particle is affected.  The PTO explained the inventors’ method as using quantum entanglement “to change the characteristics of one substance via the manipulation of a completely physically separate substance.”  The PTO did not dispute the existence of quantum entanglement, but said that the phenomenon has been seen in very specific conditions for only a fraction of a second.

The validity of a United States patent can be challenged in federal court litigation.  Patents can also be challenged in the U.S. Patent and Trademark Office, which, in most cases, is a quicker and less costly process.

The PTO provides three procedures by which a patent can be challenged: inter partes review (IPR), post grant review (PGR), and ex parte reexamination.  In IPRs and PGRs, the challenger and the patent owner both participate, and the proceedings are handled by the Patent Trial and Appeal Board (PTAB).  In an ex parte reexamination, the challenger is not involved after the request for reexamination has been filed, and the proceeding is handled by the PTO examiners.

In IPRs and PGRs, anyone except the patent owner may file a petition to challenge the patent.  The filing fees are high, $41,500 for an IPR and $47,500 for a PGR, with additional fees depending on the number of claims challenged.  The proceedings are handled by a three-judge panel of administrative judges with technical background in the field of the patent.  There are two phases in these proceedings.  The first phase consists of the filing of the petition by the challenger, the filing of a response by the patent owner, and the decision whether to institute the IPR or PGR by the PTAB.  If the PTAB institutes the IPR or PGR, then the second phase (the trial phase) begins.  The second phase consists of discovery (more limited than in litigation), briefing, an oral hearing, and a final written decision by the panel.  The entire process from institution to the final decision should take no more than 12 months.  The parties may appeal the decision to the Federal Circuit Court of Appeals.

Is it possible to legally protect an idea?  The answer is: not really.

Intellectual property is intangible personal property.  There are four types of intellectual property that are protected by law:  patents, copyrights, trademarks, and trade secrets.  A separate set of laws governs each one.  Although ideas may be intangible personal property, ideas do not

In my last column, I discussed the first argument that should be made in overcoming an obviousness rejection made by the patent examiner in a patent application.  If possible, the applicant should argue that the examiner has failed to establish a prima facie case of obviousness because the examiner did not make the required factual findings.  However, there are several additional arguments that may be applicable.

First, in relying on prior art references for the rejection, the examiner cannot pick and choose only one aspect of a prior art reference and exclude other aspects of the reference or ignore the central teaching of the reference.  “It is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position, to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one of ordinary skill in the art.”  In re Wesslau, 353 F.2d 238 (CCPA 1965).
