The thesis that anticipated the patent
A PhD student develops a low-cost method of preparing a catalyst support. Her thesis is accepted in March and uploaded to the university's open repository the same month. The technology transfer office learns about the work in August, is impressed, and files a patent application in October naming her and her supervisor.
What is the status of the application?
The repository is a publication
The test for prior art is whether the document was available to the public before the priority date. A thesis in an open institutional repository, downloadable by anyone, is available to the public from the day it goes up.
So the March upload is prior art against the October filing - and it is her own work, described in full, which makes it the most damaging kind of citation. It discloses the invention completely.
Whether section 31 helps
Section 31(d) covers a paper read by the true and first inventor before a learned society, or published with his consent in the transactions of such a society, with twelve months from the reading or publication. A thesis deposited in a university repository is not that.
Embargo periods exist at most universities precisely to manage this. Had the thesis been embargoed for six months, the October filing would have been in time.
What should have happened
- Disclosed the invention to the technology transfer office before submitting the thesis, not after.
- Requested a repository embargo for long enough to allow a filing decision.
- Filed a provisional before submission - a thesis chapter usually contains more than enough disclosure.
- Built a standing rule into the department: no submission or upload before an IP check.
For researchers, the order of publication and filing is worth more than almost any other decision they will make.
This scenario is a composite teaching example written by Ragulika IP. It does not describe any real client, application or matter, and any resemblance to a specific case is coincidental.

Can a thesis destroy the novelty of your own invention?
Yes, if the public could obtain and read it before your priority date. A thesis in an open institutional repository is a publication from the day it goes up.

Usually at repository deposit, which can be weeks after acceptance and months before any journal article. That deposit date is the one that matters.
Thinking about filing?
Before anything is drafted, the useful work is establishing what is already public, what is genuinely yours, and what you can honestly claim.
