for getting patent protection abroad and concrete
suggestions for nding the necessary resources to help
you do this
• an overview of the alternative and supplementary
forms of protection available for inventions, such
as trade secrets, copyrights, trademarks, and unfair
competition law, and
• detailed information and advice on how to
commercially evaluate, market, and license your
invention.
One purpose of this book is to save you money.
According to the American Intellectual Property
Association, the average cost of preparing a minimally
complex patent application is approximately $8,500;
preparing a relatively complex application—for example, an
application for a chemical, biotech, mechanics, electronics,
or data processing invention—costs between $11,500 and
$15,500. You may not be able to aord these fees, and even
if you can, it still pays to do it yourself. By following the
instructions set out in this book, you’ll not only save on
attorney fees, but you’ll be personally involved in every step
of the patenting process. Aer all, you know your invention
better than anyone else, and assuming you’re willing
and able to wade through a number of patent rules and
technicalities, you’re the best person to patent it.
I think of the book as a great equalizer, since it provides
the know-how to enable the garage-shop or basement do-
it-yourselfer to get as good a patent as a large corporation.
It provides the legal tools necessary for inventors (whether
large or small) to provide rst-class legal protection for
checklists we have provided throughout this book.
C. Using an Attorney
Even if you do choose to work with an attorney, or have
one available to you through the process, you’ll nd that
this book allows you to take an active role in the process,
do a better job of monitoring your attorney (no trivial
consideration), and greatly adds to your understanding
of the ways in which the law is willing to protect your
invention. No matter how competent an attorney is, the
client who understands what’s going on will always obtain
better service. Indeed, many corporate legal departments
use this book to educate their inventors and support
personnel to deal with patent attorneys and to protect their
inventions more eectively.
I have seen a number of inventors who were victimized
by their attorney (or agent) by allowing the attorney to le
an application or continue prosecution at great expense
even though the invention had a serious commercial
drawback or was mostly anticipated by prior art. Had they
considered the comments in this book, taken more interest,
and followed what the attorney and/or the PTO was doing,
they would have known that it would have been unwise to
continue. By terminating at an earlier stage, they could have
saved hundreds, or even thousands of dollars.
YOUR LEGAL COMPANION|3
D. Should You Do It Yourself?
e big question is, of course, even though many if not most
inventors can le and handle their own patent application,
should you do so on your own or hire an expert? Aer
all, you probably hire people to do all sorts of things for
making the do-it-yourself versus hire-an-attorney decision.
e best answer for some inventors may be to do some of
both. Using this approach, diligent inventors will do much
of the patent work themselves, only consulting with an
attorney at an hourly rate if snags develop, or to check the
patent application before submission.
Proposed Legislation at May Affect Your Patent
As this edition goes to press, important changes have been
proposed in the patent rules and laws. If implemented, these
changes will likely reduce the strength of patents. Some
powerful entities, mainly computer,software, and financial
servicecompanies, are in favor of these changes. Other
powerful entities, mainly drug companies, independent
inventors, Nobel laureates, and some legislators, want to keep
patents strong and thus are opposed to these changes. e
winner will be determined to a large extent by the influence
of each side over our legislators. Here is a status report as of
this edition (February 2011).
New Rule Changes Halted: e PTO issued new rules
regarding (a) the number of applications that may be
permitted in a chain of continuing applications, and (b)
the number of claims that may be filed. A number of
organizations have sued the PTO, contending that these
changes go beyond the PTO’s powers. A trial court tentatively
agreed and has issued a temporary injunction, ordering
the PTO not to implement the new rules until the issues
are resolved after a full trial. However, the appellate court
reversed part of the trial court’s decision, holding that the
PTO may limit the number of applications in a chain. Check

We realize that Patent It Yourself is a big book, and we hope
you will read it from cover to cover to get a full picture of the
field of patents and inventions. However if you don’t have
the time, this Quick-Start Guide will tell you where to look to
accomplish a specific task.
Task What to Read or Do
You’ve invented something and you want to
protect it.
Follow the RESAM procedure (Chapter 1):
Record the invention properly or file a Provisional Patent Application
(Chapter 3).
Evaluate commercial potential to see if it will sell (Chapter 4).
Search it for patentability to see if you will be able to get a patent
(Chapters 5 and 6).
Apply for a patent (Chapters 8 through 10).
Market it to a suitable company (Chapter 11).
You have a patent and want to license or sell it. Read Chapter 11 on Marketing.
You have a patent that may be infringed. Read Chapter 15 to learn how to determine whether it’s infringed and how
to go after the infringer.
You have a patent and want to maintain it. Read Chapter 15 on Maintenance Fees.
You have a patent and want to sell or license it. Reach Chapter 16 on Assignments and Licensing.
You want to learn about all forms of intellectual
property.
Read Chapters 1 and 7.
You want to determine whether your invention
will sell.
Read Chapter 4 on Evaluating Commerciality.
You want to see if your invention is patentable. Read Chapters 5 and 6 on Patentability and Searching.
You want to get a monopoly on your invention
abroad.

• new design patent infringement standards as
established in the Egyptian Goddess, Inc. v. Swisa, Inc.
case.
F. How to Use Patent It Yourself
e book is organized primarily for chronological use,
starting with an overview of the entire intellectual property
eld (which includes patents, trademarks, copyright, and
trade secret law). en it sequentially covers the steps most
inventors will take to monopolize and prot from their
inventions. I strongly recommend that you rst read the
book all the way through, skimming lightly over the many
chapters that actually tell you how to do things.
In this way you’ll rst get an overview of the patent forest
before you return and deal with the individual steps (trees)
necessary to fully protect your invention.
roughout the book I refer to a number of forms and
in many instances reproduce them in the text. A tear-out
or copyable version of each is also located in Appendix7
for your use, and all PTO forms can be downloaded from
the PTO website. If you don’t have Internet access, I recom-
mend that you make photocopies of PTO forms so you’ll have
ample spares for dras and extra copies for your records.
Also throughout the book I refer to various statutes
and governmental administrative rules, mostly in the
patent area. I use standard forms of legal citation; these are
interpreted as follows:
• 35 USC 102 = Title 35 of the U.S. Code, Section 102
• 37 CFR 1.111 = Title 37 of the (U.S.) Code of Federal
Regulations, Section 1.111.
