The hidden prices of securing innovation: The manifold impacts of obligatory invention secrecy
Daniel P. Gross 20 April 2022
Obligatory secrecy is without doubt one of the most imposing discretionary powers that the US Patent and Trademark Workplace (USPTO) and different patent places of work possess. Although maybe not broadly recognized, the USPTO has the authorized authority to order corporations and inventors to keep up the secrecy and droop the examination of innovations in patent functions whose disclosure could pose dangers to nationwide safety – thereby not solely withholding mental property (IP) rights, but additionally successfully impounding new innovations. In distinction to obligatory licensing (Moser and Voena 2012, Watzinger et al. 2017, Watzinger et al. 2020), obligatory secrecy seeks to suppress the dissemination of innovation, and imposes considerably higher prices and constraints on the inventors involved.1
The coverage’s main objective is to guard home invention from (mis)appropriation by overseas rivals. Obligatory secrecy is invoked in odd occasions with cautious discretion on tens to tons of of patent functions a yr; however in occasions of disaster, the prospects for its use develop, and rising pressures of overseas technological competitors over the past decade have prompted new consideration of drastically increasing its use to ‘economically vital’ innovation (77 F.R. 23662).
Little is understood about how obligatory secrecy impacts innovation. Its broad invocation, nonetheless, shouldn’t be with out precedent: throughout WWII, the USPTO ordered over 11,000 patent functions into secrecy, masking innovations as numerous as radar, cryptography, and artificial supplies.2 The overwhelming majority of those secrecy orders have been rescinded when the struggle ended. The scope and scale of the coverage, and its abrupt conclusion, current a uncommon alternative to check the consequences of obligatory secrecy on innovation and diffusion whereas shedding mild on the worth of patents and the ways in which formal IP rights can intrude with odd creative and industrial exercise.
The WWII experiment
In a forthcoming article (Gross 2022), I take advantage of this historic experiment to check the consequences of obligatory secrecy on three outcomes it implicates: incentives for innovation, diffusion, and follow-on invention.
I uncover a number of findings. First, corporations which obtained secrecy orders at excessive charges through the struggle shifted their patenting away from the know-how areas wherein they have been affected, and a few quickly stopped patenting altogether. This was notably true for corporations which weren’t concerned within the wartime analysis effort. Second, the patents of corporations which stayed secret for lengthy intervals have been additionally much less prone to be cited by future patents. Third, innovations ordered to stay secret have been – maybe unsurprisingly – quickly precluded from being commercialised. Collectively, these outcomes level to plenty of the potential prices of obligatory secrecy, which distorted the path of invention and undermined agency investments in innovation. But the coverage seems to have labored as meant: new phrases in titles of secret patents noticed restricted point out in patent textual content and the broader literature till after the struggle ended.
Discovering secret innovations
Obligatory secrecy has its origins in WWI. Close to the top of the struggle, Congress authorised the USPTO to order that innovations in patent functions be stored secret each time disclosure “could endanger the profitable prosecution of the struggle”. This authority ended with the struggle itself. In 1940, with WWII underway and the US bracing for entry, the regulation was resuscitated. Secrecy orders have been indefinite in length till rescinded. Violations have been punishable by lack of patent rights, as much as a $10,000 advantageous and two years in jail, and at worst, the lack of all current patents and a ban on future submitting.
The very concept that ‘secret’ invention might be studied is itself paradoxical: how can one observe what’s explicitly secret? On this case, utilizing the archival information of the businesses which suggested USPTO on the issuance of secrecy orders, I recognized 8,475 patent functions which have been ordered into secrecy in WWII – round 75% of the true whole of 11,200 described in administrative information – and an extra 20,000 functions evaluated for secrecy however disapproved, which I hyperlink to granted patents.
The know-how areas of those secrecy orders mirrored the priorities of the struggle effort. Desk 1 lists the highest ten affected patent courses, which incorporates know-how areas like cryptography, radar and digital communication, artificial supplies, petroleum refinement, and nuclear vitality. On the peak of the struggle, greater than half of all new patent filings in these courses have been sequestered.

Notes: Desk lists the ten patent courses with the very best fractions of functions from 1939–1945 positioned in secrecy, in descending order, and the maximal fraction of functions in any single yr ordered secret. Information for finally granted patents solely.
The results of obligatory secrecy
Utilizing these information, I first evaluate the tendency for corporations that patented in a given know-how space earlier than the struggle to take action once more after the struggle, as a perform of the depth with which secrecy orders in that space have been imposed through the struggle. Assignees extra closely affected by obligatory secrecy have been extra prone to cease patenting in know-how areas the place they have been affected, an impact that persevered by means of 1960. A better have a look at the outcomes by subsample gives additional clues: these results are primarily pushed by corporations not concerned within the wartime analysis effort (Gross and Sampat 2020) – that’s, and not using a authorities buyer. I then present that these corporations have been much less prone to patent in any respect. Utilizing a pattern of specialty chemical catalogues from the DuPont chemical firm, I additionally present that chemical substances that first appeared in a patent with a secrecy order have been much less prone to be bought in catalogues till the late Nineteen Forties, indicating that secrecy orders have been an obstacle to the industrial sale of merchandise they coated – one of many many causes they could have distorted or discouraged the path of agency patenting.
Turning consideration to cumulative innovation, I present that patents with lengthy secrecy phrases have been much less prone to be cited by future patents than these with shorter phrases, particularly when proscribing focus to patents filed by corporations that weren’t wartime authorities R&D contractors. No such results dogged the patents formally evaluated for secrecy however not ordered secret, which serves as a placebo. These patterns are pushed by non-self-citations and maintain with text-based (somewhat than citation-based) measures of follow-on invention, additional reinforcing the end result, which suggests this coverage could have worn out a full technology of follow-on invention.
However did the coverage work? To reply this query, I study the usage of new technical phrases from secret patents within the patent’s full textual content and within the broader written discourse, through the Google Books corpus of scanned works. Evaluating the usage of phrases that first appeared in secret patents to non-secret patents, by yr, I discover that phrases from secret patents – similar to “radar”, “fission”, or “penicillin” – weren’t used at differential charges previous to 1945. However after the struggle, use of phrases from secret patents discretely and completely jumps. As is the case all through the paper, there are not any such results for phrases from patents evaluated for secrecy however not ordered secret. The sharp soar in the usage of these phrases after secrecy orders have been lifted in 1945 suggests the coverage was efficient at averting disclosure.

Broader implications
This historic experiment presents plenty of classes for present IP analysis, coverage, and technique.
Primary ideas of each mental property rights and scientific openness have lengthy been enshrined in US regulation and coverage, with the unique Patent Act of 1790 requiring inventors to reveal their innovations in change for property rights. Obligatory secrecy immediately defies these objectives, undoing the benefits that mental property rights are meant to foster.
The outcomes of this paper illustrate what can occur when these advantages are withheld, even quickly: patenting could decline or shift in direction of protected topics, and industrial impacts and follow-on invention could also be stymied. Although WWII was a rare time, the home US economic system – not like Europe’s – was nonetheless functioning. The proof is thus suggestive of the impacts an identical revocation of IP rights and disclosure could have in different crises and even in common occasions.
Not all corporations are prone to be equally affected by obligatory secrecy. Some could even stand to profit. Proscribing data flows creates a dynamic trade-off: corporations lose entry to details about rivals that may advance its investments in innovation in the present day, however its rivals do as nicely, averting competing innovation tomorrow. These restrictions is likely to be advantageous for incumbents, who can earn rents on previous R&D investments when innovation and entry are stymied. Equally, the abrogation of formal IP rights could also be good for corporations that don’t rely closely on them and are capable of defend their IP by different means. In line with this chance, I discover that enormous corporations have been much less affected.
Lastly, this paper speaks to the position of data within the functioning of the broader innovation system. Entry to state-of-the-art scientific and technical information is usually a key enter to technological progress (Iaria et al. 2018, Biasi and Moser 2021, Furman et al. 2021, Hegde et al. 2021). Authorized students typically argue that patent paperwork aren’t themselves an vital supply of data (e.g. Roin 2005). Obligatory secrecy imposes considerably broader restrictions on disclosure than stopping patent publication alone. Their results on subsequent invention are thus suggestive of the worth of unrestricted data flows in supporting cumulative innovation.
