The Rising Importance of Trade Secret Protection for AI-
Related Intellectual Property
Artificial intelligence (AI) has quickly become one of the pillars of the modern economy.
According to one widely cited study from 2017, AI could contribute up to $15.7 trillion dollars to the
global economy by 2030.
1
That prediction is already coming to fruition. According to a White House
report on AI from February 2020, “AI is already having a substantial economic impact, not only for
companies whose core business is AI, but also for nearly all other companies as they discover the need
to adopt AI technologies to stay globally competitive.”
2
The recognition of the importance of AI is
both broad and worldwide. Russia’s Vladimir Putin has gone as far as to state that “whoever becomes
the leader in [AI] will become the ruler of the world.”
3
It is thus no surprise that companies are heavily investing to protect the intellectual property
generated from their investments in AI technology.
4
The question becomes how to best protect those
investments in this critical space. For example, an autonomous driving company may be looking at
its AI training data (i.e. records of previous test drives), the artificial neural network implementations
generated from that training data (i.e., the software that helps the car drive itself), and assortments of
other source code necessary to operate an autonomous car. For each of these elements, the company
must examine what aspects are patentable, subject to trade secret protectionor both. The wrong
decision on these topics could result in the company being left with no meaningful intellectual
property protection for its most important research and development.
But patenting AI technology today can be difficult. Due to the prohibition on patenting
abstract ideas, acquiring meaningful patents on artificial intelligence systems is not straightforward.
Thus companies are increasingly turning to trade secret protection to protect their AI-related
intellectual property. This article explores the tradeoffs between patents and trade secrets in the AI
sector. It then describes how trade secrets have become essential tools for companies to protect their
AI-related intellectual property. Finally, it concludes with practical guidance for in-house counsel on
how to leverage both patents and trade secrets to best protect valuable intellectual property regarding
AI.
I. What is “artificial intelligence”?
First, a word on terminology. Like many popular technology areas, companies have been
invoking the term “artificial intelligence” to describe their products at the earliest opportunity—even
where the underlying technology does not fit within the established definition of artificial intelligence.

For purposes of this article, artificial intelligence generally refers to technology that, in some sense,
mimics human intelligence. In particular, AI under this definition permits computers to perform some
task without being expressly programmed to do so. To that end, this article will focus on machine
learning, neural networks, related training models, algorithms and data.
II. Patents versus Trade Secrets The Tradeoff of Public Disclosure
Patents confer a legal right to exclude others from making, using, selling, and importing the
invention claimed for a number of years. But, in order to take advantage of this government-
sanctioned monopoly, the inventor must disclose the invention to the public with enough detail such
that the invention can be recreated by others in that field. This quid-pro-quoa disclosure of the
invention to the public in return for a limited-in-time monopoly on the inventionis one fundamental
underlying policy objective of US patent law.
By contrast, trade secrets, as the name suggests, protect information that is “secret.” Trade
secrets can provide protection for any information where the owner “has taken reasonable efforts to
keep such information secret” and the information “derives independent economic value, actual or
potential, from not being generally known” to other persons.
5
Both federal and state law provide
protection for trade secrets. Historically, trade secret protection has been applied to a wide variety of
subject matter, including compilations of public data,
6
source code,
7
schematics, diagrams, and
customer listsamongst many other pieces of information.
In many ways, trade secret law can be broader or more flexible than patent law. Unlike patents,
trade secret protection can be obtained without any application or registrationit arises automatically
if the trade secret owner takes appropriate steps to ensure the information is secret and so long as it
provides a competitive benefit. Trade secret protection can also theoretically last as long as the
information is kept a secret. And trade secret law also “protects items which would not be proper
subjects for consideration for patent protection under 35 U. S. C. § 101.” Kewanee Oil Co. v. Bicron Corp.,
416 U.S. 470, 482-3 (1974). For example, a list of customers could be protected as a trade secret, but
certainly not as a patent.
But in other ways trade secret protection is weaker than patent law. Importantly, independent
development is a defense to trade secret misappropriation, but not for patent infringement. As
explained by the Supreme Court in Kewanee in 1974:
Trade secret law provides far weaker protection in many respects than the patent law.
While trade secret law does not forbid the discovery of the trade secret by fair and
honest means, e. g., independent creation or reverse engineering, patent law operates
“against the world,” forbidding any use of the invention for whatever purpose for a
significant length of time. The holder of a trade secret also takes a substantial risk that

See, e.g., 18 U.S.C. 1839(3) (Federal Defend Trade Secrets Act, definition of “trade secret”); Cal. Civ.
Code § 3426.1(d) (California Uniform Trade Secrets Act, definition of “trade secret”).

trade secret); Strategic Direction Grp., Inc. v. Bristol-Myers Squibb Co., 293 F.3d 1062, 1065 (8th Cir.
2002).

the secret will be passed on to his competitors, by theft or by breach of a confidential
relationship, in a manner not easily susceptible of discovery or proof. Where patent
law acts as a barrier, trade secret law functions relatively as a sieve.
Kewanee, 416 U.S. at 489-490 (footnote and citation omitted).
This view is not universal. One can ask whether Coca-Cola, the holder of one of the most
famous trade secretsthe formula for Coca-Colawould agree with this view.
8
More to the point,
times have changed since the Kewanee decision in the 1970’s. Under recent Supreme Court precedent,
for certain types of innovations related to AI, the pendulum has swung away from patent protection
towards trade secret protection.
III. The Difficulties in Patenting AI
Alice
and Abstract Ideas
Recent years have seen a rapid acceleration in the number of patent applications directed to
inventions in the field of artificial intelligence. More than half of all AI-related patent applications
have been published since 2013.
9
Within that time, applications related to machine learning have
grown by an average of 28% each year, applications related to computer vision have grown by an
average of 46% each year, and applications related to robotics and control methods have grown by an
average of 55% each year.
Despite this surge in applications, however, there are potential pitfalls to seeking patent
protection over AI-related inventions. In particular, to receive a patent, the patent must claim patent-
eligible subject matter under 35 U.S.C. § 101. One category that is ineligible for patent protection is
abstract ideas. Over the last 15 years, the clear trend in the case law is applying the prohibition on
patenting abstract ideas more strictly to software-centric inventions.
The current law governing subject matter eligibility comes from the Supreme Court’s 2014
decision in Alice Corp. v. CLS Bank International.
10
Under Alice and its progeny, courts are directed to
“first determine whether the claims at issue are directed to one of those patent-ineligible concepts,
and if so, then as what else there is in those claims.”
11
If they find the invention directed to a patent-
ineligible concept (e.g., an abstract idea), a court “must examine the elements of the claim to determine
whether it contains an inventive concept sufficient to transform the claimed abstract idea into a patent-
eligible application.”
12
Since almost all AIrelated inventions are implemented through software processes running
on computer hardware, patent eligibility for these inventions are generally governed by the same legal
8
See Coca-Cola Bottling Co. of Shreveport v. Coca-Cola Co., 107 F.R.D. 288, 294 (D. Del. 1985) (“The
written version of the secret formula is kept in a security vault at the Trust Company Bank in Atlanta, and
that vault can only be opened by a resolution from the Company's Board of Directors. It is the Company's
policy that only two persons in the Company shall know the formula at any one time, and that only those
persons may oversee the actual preparation of Merchandise 7X. The Company refuses to allow the identity
of those persons to be disclosed or to allow those persons to fly on the same airplane at the same time.”).

principles applied to other software patents. But in recent history, the application of patent eligibility
standards to these kinds of software-based inventions has proven unpredictable.
13
Some guidance has also recently emerged from the PTO, which has faced its own challenges
implementing the post-Alice jurisprudence into its examination processes. Indeed, the PTO has
acknowledged that [p]roperly applying the Alice/Mayo test in a consistent manner has proven difficult,
and has caused uncertainty in this area of the law.The PTO recently instituted new guidance in 2019
regarding the application of this developing case law to pending patent applications, attempting to
provide a more concrete framework for application of Alice and its progeny based on enumerated
groupings of abstract ideas.
14
While this guidance is relatively new, initial review decisions since its
introduction suggest a potentially friendlier environment for AI-related applications.
15
Despite this guidance, there remain serious risks in seeking patent protection over AI-based
inventions. Given the limitations articulated in Alice and its progeny, it is unclear how many of the
AI-related patents that have made their way through the U.S. Patent Office would survive in eventual
litigation. Hyper Search, LLC v. Facebook, Inc., No. CV 17-1387-CFC-SRF, 2018 WL 6617143, at *10
(D. Del. Dec. 17, 2018) illustrates how some courts are applying Alice to invalidate patents related to
artificial intelligence:
Claim 1 of the ’412 patent recites generic computer functionality such as a “neural
network module” and a “server.” (’412 patent, col. 19:49-67) Limiting the use of an
abstract idea “to a particular technological environment” does not transform an
abstract idea into a patent-eligible invention. Alice, 134 S. Ct. at 2358 (internal citations
omitted). The specification states that neural networks were well-known in the art, and
the inventors stated that the alleged invention is not limited to neural networks but
rather to “any artificial intelligence agent.” (’412 patent, col. 7:45-8:5, 19:23-27) Courts
have previously found that claims reciting neural networks to be unpatentable for
failing to recite more than an abstract idea. See Neochloris, Inc. v. Emerson Process Mgmt
LLLP, 140 F. Supp. 3d 763, 773 (N.D. Ill. 2015) (finding patent claims including “an
artificial neural network module” invalid under § 101 because neural network modules
were described as no more than “a central processing unit a basic computer’s brain”).
13
In the aftermath of Alice district courts and the Federal Circuit have expressed difficulty in consistently
applying this framework. See, e.g., Interval Licensing LLC v. AOL, Inc., 896 F.3d 1335, 1355 (Fed. Cir.
2018) (Plager, J., dissenting) (describing “uselessness of the abstract notion of ‘abstract ideas’ as a criterion
for patent eligibility”); Berkheimer v. HP Inc., 890 F.3d 1369, 1374 (Fed. Cir. 2018) (Lourie, J.,
concurring); see also Testimony of Hon. Paul R. Michel, The State of Patent Eligibility in America, Part I:
Hearing Before the Subcommittee on Intellectual Property of the S. Comm. On the Judiciary, 116
th
Cong. 2
(June 4, 2019) (recording testimony of former Federal Circuit Judge Paul Michel that “recent cases are
unclear, inconsistent with one another and confusing,” and that he “cannot reconcile” their outcomes or
“predict outcomes in individual cases with any confidence.”).
14
See https://www.govinfo.gov/content/pkg/FR-2019-01-07/pdf/2018-28282.pdf. Note that while these
guidelines to not have the force of law, they are themselves based on a distillation of post-Alice cases.
15
See, e.g., https://e-foia.uspto.gov/Foia/RetrievePdf?system=BPAI&flNm=fd2018007443-10-10-2019-0
(reversing rejection of claims that “recite monitoring operation of machines using neural networks, logic
decisions trees, confidence assessments, fuzzy logic, smart agent profiling, and case-based reasoning” on
the grounds that using “neural networks” in the context of monitoring a machine did not qualify as an
abstract method of organizing human activity and that this “computational complexity” removed the claims
from the realm of abstract mental processes).
5
Id. at *10. After making these findings, the Court then held the asserted patent invalid
as improperly claiming only abstract ideas. Id.
Similarly, in Purepredictive, Inc. v. H20.AI, Inc., No. 17-CV-03049-WHO, 2017 WL 3721480, at *5 (N.D.
Cal. Aug. 29, 2017), aff'd sub nom. Purepredictive, Inc. v. H2O.ai, Inc., 741 F. App'x 802 (Fed. Cir. 2018),
the Court invalidated an asserted patent directed to automating predictive analytics:
Turning to this case, I agree with H20 that PPI’s claims are directed to a mental process
and the abstract concept of using mathematical algorithms to perform predictive
analytics. The method of the predictive analytics factory is directed towards collecting
and analyzing information. The first step, generating learned functions or regressions
from datathe basic mathematical process of, for example, regression modeling, or
running data through an algorithmis not a patentable concept. See DDR Holdings,
LLC v. Hotels.com, L.P., 773 F.3d 1245, 1256 (Fed. Cir. 2014) (“We know that
mathematical algorithms, including those executed on a generic computer, are abstract
ideas.”). That the “function generator module” described in the '446 Patent “may
generate hundreds, thousands, or millions of learned functions, or more,” '446 Patent
at 9:5557, does not change this conclusion.
Id. at *5.
While each of these patents stand on their own and the decisions do not indicate that any
future AI-related patents are necessarily invalid (or valid), they stand as guideposts that companies
should be mindful of when considering patenting artificial intelligence inventions. Compare id. with SRI
International, Inc. v. Cisco Systems, Inc., 930 F.3d 1295 (Fed. Cir. 2019) (finding patent claiming “detecting,
…suspicious network activity based on analysis of network traffic data” directed towards patentable
subject matter).
Finally, some AI-related innovations are simply not eligible to receive patent protection in the
first place. For example, raw data collected for use in machine learning algorithms is not patentable
in and of itself. That raw data combined with a conventional and well-known machine learning
algorithm, also may not be patentable even though the result may be incredibly valuable to the
company. Considering these limits and potential risks, many companies are turning to alternatives
means to protect their valuable intellectual property in the AI spacenamely, trade secrets.
IV. Trade Secrets An Apt Tool for Protection AI Intellectual
Property
While it’s hard to track the exact number of trade secrets related to AI that are being closely
held by organizations around the worldas they are by their nature secretit is likely that most
intellectual property generated in the United States today related to AI is being protected through the
use of trade secrets. While specific details remain confidential in light of strict confidentiality
procedures, courts have already indicated that certain areas of information related to AI are protected
6
as trade secrets, such as algorithms, source code, and the way a business utilizes AI to implement
machine learning.
16
There are certain distinct advantages to trade secretsno filings fees, protection in real-time,
theoretically unlimited length of protection, and broadly eligible subject matter. For AI in particular,
there are several reasons why trade secrets are particularly valuable and suitable for intellectual
property protection as compared to patents:
AI technology is rapidly developing and improving
17
at a rate the patent system is not
designed to keep up with.
Companies can create highly valuable intellectual property by understanding and
creating a knowledge base about what technology does not work. While this
knowledge does not qualify for patent protection, it can be protected as a “negative
trade secret.”
18
If another company were to misappropriate this information, it could
short circuit the need for years of research and development going down the wrong
path.
Some of the most important technology in AI is implementation know-how that is not
suitable for patent protection. For example, because autonomous cars are not yet
widely on the market, some companies have kept their technology secret from their
competitors to gain an advantage.
19
As discussed, many AI developments are software-based, making patents more
difficult to obtain under Alice.
Breaking down AI and machine learning systems into three stages, we can see the benefits of trade
secret protection available at each one:
Stage 1: Data Collection and Training Training data itself may not be protectable
as a patent, but a collection of dataeven where that data comprises otherwise public
16
See e.g., LivePerson, Inc. v. 24/7 Customer, Inc., 83 F. Supp. 3d 501, 514 (S.D.N.Y. 2015) (finding
algorithms based on artificial intelligence eligible for trade secret protection).
17
See Nine charts that really bring home just how fast AI is growing,” MIT Technology Review (Dec. 12,
2018), available at https://www.technologyreview.com/s/612582/data-that-illuminates-the-ai-boom/
(describing how “the state of the art is improving fast” in AI).
18
Cal. Civ. Code § 3426.1(d); accord XpertUniverse, Inc. v. Cisco Sys., Inc., No. CIV.A. 09-157-RGA,
2013 WL 867640, at *2 (D. Del. Mar. 8, 2013), aff'd (Jan. 21, 2015) (“The definition [of a trade secret in
Cal. Civ.Code § 3426.1(d)] includes information that has commercial value from a negative viewpoint, for
example the results of lengthy and expensive research which proves that a certain process will not work
could be of great value to a competitor.”).
19
The implementation know-how must have potential or actual economic value to qualify as a trade secret.
Proprietary ways of doing the same thing that others in the same field do are not trade secrets. Agency
Solutions.Com, LLC v. TriZetto Grp., Inc., 819 F. Supp. 2d 1001, 1017, 1021 (E.D. Cal. 2011)). If
particular functionality of software is known or knowable without resort to clandestine means, then some
aspects of the code may not comprise a trade secret even though the associated source code may itself be
kept secret. But see id. (Note, however, that while the way something is done is not a trade secret, some
discrete fact concerning that way could conceivably be a trade secret.).
7
informationcan be protected as a trade secret.
20
This data can be highly valuable.
According to The Economist, “[t]he world’s most valuable resource is no longer oil, but
data.”
21
Stage 2: Neural Networks and Algorithms There may be difficulty patenting
algorithms alone under Alice. But the algorithm or neural network design and
implementation are eligible for trade secret protection if the statutory requirements are
satisfied.
Stage 3: Output of AI System Output data is potentially protectable as a trade
secret if the relevant information is sufficiently secret and not generally known.
While trade secrets are increasingly important for AI companies, there is one major drawback
in utilizing trade secrets: protection is only afforded to the extent the intellectual property can be kept
secret. Keeping software a “secret” can be challenging and operationally taxing for several reasons:
(1) given the turnover at technology companies, strong employment agreements are needed to ensure
departing employees are legally required to keep trade secrets secret; (2) given the ease of “stealing”
softwarewhich can be as easy as downloading code to a USB drivestrong cybersecurity policies
need to be created and enforced;
22
(3) because reverse engineering can be a defense to trade secret
appropriation,
23
software needs to be designed and deployed in a way to ensure reverse engineering is
not possible; and (4) in order to conduct business, it is often necessary to share technology widely
with employees and partners, which increases the risk that a trade secret could be disclosed publicly.
24
In light of these concerns, maintaining trade secret protection can incur meaningful costs for
a company and requires significant ongoing vigilance. Companies relying on trade secret protection
can take the following steps to help ensure the protection of their AI innovations:
(1) Require third parties to sign non-disclosure agreements and restrictive licenses so they
cannot disseminate trade secret information in unauthorized ways;
25
(2) Appropriately label company confidential information;
20
See N. Am. Deer Registry, Inc. v. DNA Sols., Inc., No. 4:17-CV-00062, 2017 WL 2402579, at *8 (E.D.
Tex. Jun. 2, 2017).

longer-oil-but-data
22
Several high-profile cases have involved so-called “insider threats” where an employees has taken
software or trade secret data to use at a competitor.
23
See, e.g., Sargent Fletcher, Inc. v. Able Corp., 110 Cal. App. 4th 1658, 1670 (2003) (“Evidence of
independent derivation or reverse engineering directly refutes the element of use through improper
means.”); N. Am. Deer Registry, Inc. v. DNA Sols., Inc., 2017 WL 2402579, at *7 (E.D. Tex. June 2, 2017)
(trade secret is not misappropriated if there is reverse engineering or independent derivation).
24
See LivePerson, Inc. v. 24/7 Customer, Inc., 83 F. Supp. 3d 501, 514 (S.D.N.Y. 2015) (denying motion
to dismiss trade secret claim where plaintiff demonstrated that it included confidentiality provisions and
prohibitions against reverse engineering, infringing, or disrupting its technology, as well as confidentiality
and limited-use license restrictions in its client agreements).
25
Note that certain jurisdiction, notably California, place considerable restrictions on the terms of such
agreements as part of prohibitions on non-compete clauses. See, e.g., Cal. Bus. & Prof. Code § 16600.
8
(3) Review cybersecurity policies to limit the potential for unauthorized access to
information that constitutes a trade secret; and
(4) Ensure any departing employees have returned company materials and removed any
sensitive information from personal devices.
26
Ultimately, a trade secret is only protected so long as it remains a secret. Even with strict
regulations in place, companies always run the risk that the information will become public.
V. Patent vs. Trade Secret: Making the Right Decision for AI-
Related Inventions
Even though trade secrets are important to protect AI-related intellectual property, there
remain different advantages and drawbacks for both patents and trade secrets. The decision whether
to patent or keep as a trade secret a given innovation thus represents an important strategic decision
for any company.
As an initial mater, the decision between patents and trade secrets can be, but is not always,
mutually exclusive. In some instances a company can file a patent on the public-facing part of a
product, which cannot be kept as a trade secret because it is not secret. At the same time, the company
can maintain as a trade secret certain manufacturing techniques or other innovations within the
product that are not generally known.
27
In another strategy, the company may keep technology as a
trade secret while simultaneously applying for patent protection by seeking non-publication of its
patent application.
28
In this scenario, the invention could have trade secret protection for the period
of time during patent prosecution, and then patent protection once the patent issues. Of course, the
company would then be limited to the claims of the patent only.
For some AI-related inventions, it may be possible to either apply for a patent or keep the
intellectual property as a trade secret. Here are some guiding factors to consider when making these
kinds of critical decisions:
(1)
Is the innovation eligible for patent protection?
Does the innovation satisfy
the requirements of the Patent Act, including being patent-eligible subject matter
under 35 U.S.C. § 101? If not, then patents are unavailable and trade secret
protection is the best option. As discussed throughout this article, that can be the
case with many AI-related innovations and technology.
(2)
Does the innovation comprise the type of information that can be kept
secret as part of your business?
If the innovation is readily discernable from
the product itself or by other appropriate means, trade secret protection would be
26
Conversely, to avoid trade secret liability, best practices must be observed when hiring and/or
onboarding new employees who formerly worked for competitors.
27
One potential pitfall to avoid in this instance is the requirement under patent law to enable one to
practice the claimed invention. If knowledge of the contemplated trade secret is essential to practice what
is claimed, then it likely needs to be disclosed in the patent application or it risks invalidity for lack of
enablement under 35 U.S.C. § 112.
28
See 35 U.S.C. 122 (describing circumstances where patent applicant can request its application not be
published).
9
unavailable. The trade secret in that instance would not be “secret.” Thus, patent
protection would be the best option.
(3)
Is the innovation likely to become generally known soon?
Trade secrets only
protect information that is not generally known. If the innovation is one that
competitors or academia is likely to be making public relatively soon, then trade
secret protection is sub-optimal. Instead patent protection may be the best option.
(4)
How likely is the patent able to withstand an attack in litigation?
Even if
the patent may be approved by the patent office, if you believe the patent is
unlikely to withstand an attack in litigation, it may be better to keep the innovation
as a trade secret so the underlying intellectual property does not have to be
disclosed to the public.
(5)
How hard would it be to determine that another company is practicing your
invention?
The purpose of a patent is to prevent others from practicing your
invention. But if the invention is for an AI algorithm that runs on a server that
cannot be observed by the public, it may be impossible to tell which, if any,
competitors are infringing on the technology. This would make a patent less
valuable. On the other hand, if it is possible to completely reverse engineer the
invention, then a competitor can use that as a defense to any claims of trade secret
misappropriation.
29
(6)
How quickly will the invention become obsolete?
If the invention will
become obsolete quickly, the length of protection that patents provide (and the
cost and effort to file the patent), may not be worth the benefit.
(7)
How quickly can the invention be commercialized?
Conversely, if the
invention will take a long period of time to monetize, the length of protection
afforded by a patent will allow time for long-term investment and capitalization.
(8)
How hard is to describe the invention?
In order to be issued a patent, the filer
needs to describe the invention which serves both to “satisfy the inventor’s
obligation to disclose the technologic knowledge upon which the patent is based,
and to demonstrate that the patentee was in possession of the invention that is
claimed.” If an invention would be difficult or time consuming to describe in a
way that would satisfy the patent requirements, a trade secret may be more
appropriate.
29
See e.g., Kewanee Oil Co. v. Bicron Corp., 416 U.S. 470 (1974) (“A trade secret law … does not offer
protection against discovery by fair and honest means, such as by independent invention, accidental
disclosure, or by so-called reverse engineering, that is, by starting with the known product and working
backward to divine the process which aided in its development or manufacture.”). Different courts and
jurisdictions have applied this so-called “reverse engineering” defense differently: some courts have not
considered the time, expense, or effort needed to reverse engineer the trade secrete while other courts have
only allowed a reverse-engineering defense where the trade secret was “readily ascertainable
through…reverse engineering.” Compare Barr-Mullin, Inc. v. Browning, 424 S.E.2d 226 (N.C. Ct. App.
1993) to Midland-Ross Corp. v. Sunbeam Equipment Corp., 316 F. Supp. 171, 173 (W.D. Pa. 1970).
10
(9)
Is the innovation worth patenting?
Patents cost time and money to prosecute
and obtain. Not all innovations are worth that effort. For certain types of know-
how, it may be more practical to utilize trade secrets to protect the innovation
rather than filing a patent.
Trade secrets are a powerful tool for protecting AI-related innovations and are particularly
well-suited to the field. But both patents and trade secrets offer powerful ways for companies to
