I am a young postgraduate researcher, and I have developed an algorithm to measure the blood flow from echographic signals in a novel manner. I currently only have one published paper from my pregraduate years, on which I am 4th author, and it is not about my current field of research.

Long story short, my algorithm is unpublished and works quite well... so well that recently a PhD in electrical engineering from the other side of the planet saw a summary about it on the net, and sent me an email asking for some data, so that one of his undergraduate students can reproduce my program. They assure me that they won't use it for publishing, and both the PhD and his supposed undergraduate sent me several emails already. When I asked for precisions about their project, they just in essence replied: "We don't really know yet, but we would like to reproduce your work"

I don't know what to answer... moreover, the data they are asking for (a video of an echographic exam) can be found in 10 seconds on Youtube. What should I do?

    Then why don't you just point them to Youtube?

    Better safe than sorry, publish your algorithm first.

    As mmh says, you should just publish it. Tell the students that you are in the midst of writing a paper to publish the algorithm (if you write the abstract before replying to the email, it's technically true!), and you can then make the source code available with the paper under an attribution license.

1 Answer 1


I agree with both previous commenters: publish your algorithm first and then point them to the YouTube video. If you cannot or don't want to go the traditional journal publishing route, at least, consider self-publishing a paper, describing your algorithm, at a preprint or e-print server, such as arXiv. At the same time, I don't see a problem with this request, IF it involves sharing only data, but not the algorithm itself.

If you see the value of and are serious about commercialization of your algorithm, consider filing a provisional patent application with USPTO and/or Swiss patent agency. I'm not sure about possibility and details of applying for provisional patent in Switzerland, therefore, I refer you to this page, which seems to be relevant. It might be easier to skip filing provisional patent application with USPTO and file a standard one in Europe to establish the priority right (for example, see this page). Should you be thinking about going the patent route, I would definitely recommend you to consult a legal professional, specializing in intellectual property (IP) domain.

    Note: in Europe (and many more places) you cannot patent an algorithm.

    @Bakuriu: You're right - I forgot about that aspect. Nevertheless, I think that it is possible to combine algorithm with some other novel aspects and formulate a method (or, how it is frequently referred to, "method and apparatus"), which is patentable. Commented May 7, 2015 at 17:43

    Note also that you cannot patent something that has already been made public. So, if you are going the patent route, that excludes the ArXiv route. Commented May 7, 2015 at 19:30
  • @DavidRicherby: Thank you for clarification. But, I think that it is not entirely true - one has a one year grace period after public disclosure, allowing inventor to file patent application and enforce patent rights. Commented May 8, 2015 at 2:20

    @AleksandrBlekh the one year grace period only applies in the USA. For the rest of the world (or at least, any country worth owning a patent in besides the USA), there is no grace period after public disclosure - so file a patent first unless you want US only protection!
