Tell A Friend!

Generally speaking, a patent application will publish 18 months after the earliest priority date claimed. What gets published does become prior art, but the rights may never mature into an issued patent. Sometimes it can be quite interesting to look at published patent applications to get an idea about what a company or University may be working toward achieving, as Steve Brachmann does for us every week as part of our Companies We Follow series. But there are no doubt some bizarre patent applications that have published over the years, such as a method of walking through walls like a ghost. See Knowing When You Have Too Much Time on Your HandsSo you never know quite what you will get with a patent application, although the jokesters are typically kept at a minimum given the expense of filing a patent application.

Nevertheless, recently as I was talking with Paul Dougherty of The Patent Box, he indicated that he could run a search that identified the shortest patent claims. It seemed like it could be fun, and perhaps might become a new series here on IPWatchdog.com.

In terms of observations about these claims, although short some of them may be more detailed than you might think, particularly the synthetic gene that makes reference to a particular gene sequence, for example. Of course, biology and chemistry are beyond the scope of my expertise, so these claims are provided here for your consideration. Hopefully some of our regular community members, who I know do specialize in bio/chemical matters will weigh in with comments.

While the gene sequence claim is no doubt more narrow than you might think, others are almost laughably broad to the point where they have absolutely no chance of being issued. For example, there are a couple so-called omnibus claim on this list, although many were located. An omnibus claim is not allowed in the United States and basically says “I claim what is described in the specification.” That type of claiming is simply not allowed and will be summarily rejected without any meaningful, substantive examination. There are also other very short mechanical claims listed, which seem to have no chance of succeeding on a first review by the patent examiner.

The real problem is that the failure to include claims or realistic breadth means that there will be no meaningful examination provided by the examiner in the first of two substantives reviews. If such obviously overbroad claims are the ones that are in the file at the time of first examination it will be virtually impossible to obtain a patent without at least one, perhaps multiple, additional filings and amendments, all of which cost time and money for the inventor/applicant. The old saying “garbage in, garbage out” comes to mind.

If you make it simple for the patent examiner to reject your claims then you obtain no insight into the examiner’s thinking and have no idea what the best prior art is that the examiner can and will eventually use against your application. In essence, poor claiming at the outset results in prolonged prosecution that is costly and unnecessarily delays whatever the eventual outcome will be.

Now, without any further ado, what follows are some of the shortest claims Paul’s recent search uncovered. File histories available at The Patent Box for those interested.

  1. Yeah, but in many of these (I didn’t click on all), there are very detailed dependent claims. So, the subject matter is claimed in a broad-to-narrow fashion, which is ideal. Sure, the independent claim may (or may not) be overly broad, but at least the inventor took a swing at it. Including such a broad claim might decrease the likelihood of a first action allowance, but it allows the inventor to potentially get the maximum claim scope. On the other hand, if the broad claim 1 is the only claim, then I agree, it’s a bad idea.

    I’d be curious to see a report of the shortest claims from allowed patents in recent years. A lot will be the nucleic acid or protein sequence type of claim though, which is in effect, a claim that is potentially very, very long, depending on the sequence itself.

  2. Shortest claim – US3156523, deservedly granted to a noteworthy Nobel prizewinner.
    (Isn’t Google fun ?)

  3. One more note of interest – the same Google search turned up the shortest patent application – 10/035947. You spend more time laughing than reading it.
