Intellectual

BURST BALLOON
Due
diligence that is taken before corporate or patent acquisition could
unearth flaws fatal to the assets' worth.

Adversity
often is seen in hind-sight as having promoted new strengths. The
adversity of the last few years in the Nottech investment community
has led to industry maturation. In addition to obvious investment
caution and greater reliance on core business fundamentals, healthy
trends regarding technology-based intellectual property have emerged.
substantive intellectual property has continued to be recognized as
adding great capital value to high-tech enterprise.
In
the recent past, technical intellectual property was a term near-synonymous
with value and promise. Details were looked on as unimportant.
Specific
instances have been observed where independent after-the-fact studies
of patent portfolios held by acquired companies provided unwelcome
surprises. Complete disconnects were found between the portfolios
of patent protection and the products, services or developments where
protection had been an important factor in the acquisition.
Such
disconnects do not by themselves portend future corporate doom. The
news prompted corporate realization that a significant capital investment
based on perceived intellectual-properly protections was little more
than stroke. Reassessment of corporate strategies followed.
In
the wake of these and similar experiences, not to mention the evaporation
of fortunes in the recent high-tech bust due diligence in transferring
or investing in intellectual property has become a growth industry
for the intellectual-property world.
Such
due diligence is undertaken before corporate acquisition, corporate
investment patent acquisition, patent licensing and corporate capital
offerings, to name a few.
The
findings of intellectual-property due diligence can unearth flaws
fatal to intellectual-property worth. This is the extreme. Often such
findings are only first steps in the valuation process.
Scope:
The Measure of a Patent
Appropriate
due diligence requires an investigation of patent scope attributed
to the patent portfolio.
Every
patent affords a specific scope of protection unless it is found invalid
or unen forceable. Scope is defined by the claims of he patent which
are the numbered parapaphs at the end of the patent specification.
They are the measure of exclusivity afforded by the patent
First
and foremost, the plain meaning of he words and phrases in a claim
is examned for its construction.
The
patent itself, the prosecution history available from the Patent Office
and the references to prior technology considered durng prosecution
form the intrinsic informa-ion on which construction of the claims
is neasured.
With
scope defined through the above access, a meaningful comparison between
patent exclusivity, defined by scope, and the atent owner's products
or services can be made with the help of those skilled in the relevant
technology. The breadth of coverage for meaningfully excluding others
can be evaluated.
Beyond
coverage of the relevant products or services, the commercial relevance
of what is covered is appropriately reviewed through intellectual-property
dire diligence.
For
example, the novelty in the scope of coverage on a camera patent may
be in a new mechanism for winding film The corporate products are
found to use the patented winding
mechanism.
Of
course, conventional mechanism for winding film have long been known.
Terefore, the issue remains whether exclusivity on this specific patented
winding mechanism (protected technology) offers some competitive or
other advantage over conventional winding mechanisms (unprotected
technology). If not, the patent may offer little or no value.
The
breadth of scope defines the line between protected and unprotected
technology.
Intellectual-property
due diligence establishing that line supports a technical or marketing
evaluation directed to the commercial advantages of the barriers provided
by the patent portfolio.
Once
commercial advantage is resolved patent valuation is possible in the
context of exclusive intellectual-property protection as well as the
significance of the exclusive intellectual-property protection for
current or prospective products or services.
With
scope defined, infringement and validity issues can be addressed.
Infringement
issues are measured against products and processes, not patents However,
another's patent that is found to block signficantly the practical
application of a patent portfolio significantly affects the value
of such a portfolio. Scope measures that practical application for
comparison with threatening patents.
Patents are afforded a substantial presumption of validity based on
the court acknowledged rigors of examination by the Patent Office.
Even so, the presumption of validity of any given patent or any specific
claim of a patent could become vulnerable when faced with anticipatory
or highly relevant prior technology.
What is anticipatory and relevant prior technology affecting validity
and enforceability is measured in the context of claim scope. Intellectual-property
due diligence typically includes certain technology searching and
investigation of corporate records guided by claim scope.
Searches:
Placing the Patent Portfolio In Industry Context
Patents
frequently are misunderstood to provide assurance that the product
or service practicing or embodying the patented invention is free
from the infringement of other patents. Not so. For example, if a
first inventor patents the automobile without mentioning the transmission
and a second inventor patents the automobile with a transmission,
the second inventor cannot make automobiles without infringement,
with or without a transmission.
Because no infringement assurance is conveyed by a patent dire diligence
has come to include substantial infringement searching in the area
of the relevant patent portfolio. Such searching can be both to avoid
infringement and to assess whether patents block the portfolio. Various
types of searches frequently are undertaken.
Assignee searches uncover the patent positions of competitors. Due
diligence on competitive positions has been found most useful.
In-house document reviews of patents accumulated by the portfolio
owner as prior technology in the patenting process, both domestic
and foreign, as documents of earlier infringement concerns or as teaching
disclosure to aid in development are a source of likely relevant patents
which could be of concern.
Subject-rnatter searches through computer word searching and category
searching at the Patent Office are more difficult and are open-ended.
None of the above, however, can provide complete assurance that there
is no infringement.
Validity searching is less commonly undertaken in intellectral-pmperty
duel gence efforts The focus is effectively the same as used by the
patent examiner in determining patentability. Because the task is
open-ended until an anticipatory reference is found, the scope of
the task is driven by how much is to be spent Validity evahiation
of the intellectral•property portfolio based on the references
located in the assignee search and in house document reviews should,
however, be undertaken.
Corporate
Review: Avoiding Intrinsic Rot
The
enforcement of patents is subject to several defenses. Anticipation
of such defenses principally relies on technical evaluation with heightened
awareness through intellectual-property due diligence.
For example, there is a low but present requirement for operability.
Disclosure of a best mode of the invention at the time the application
was filed also is required.
A duty of candor is owed the Patent Office by patent applicants. Information
relevant to such issues is either intrinsically found in the patents
of the intellectual-property portfolio or is located through due-diligent
investigation and disclosure of the entity holding the intellectual-property
rights.
