Cost of Patent Application Preparation

Cost of Preparing a Patent Application

Costs for preparing a patent application vary depending on the complexity of the invention.  Here is one source of cost data: patent cost statistics.  Below, I discuss some highlights from the patent cost statistics and also add some other available figures.

Cost of Patent Applications – Recent Numbers

A Seattle company that I work with made of point of asking the cost question of every inventor and every patent attorney willing to comment.  The 2013-2014 numbers fall within the range of $5,000 – $6,000 for a provisional and $12,000 – $15,000 for a non-provisional.  Since the United States moved over to the First Inventor to File system, most attorneys agree that the quality (and cost) of a provisional applications is approaching that for a non-provisional application.
Personally, I encourage my clients to invest in a good provisional patent application at the onset.  That provides the strongest priority claim and also cuts down on the fees for filing a non-provisional application.  (If the provisional application is of non-provisional quality, then it takes little work to use it as a non-provisional one year later).
One major Seattle technology firm reported paying a flat per-application fee based on 3 levels of patent complexity: A = $7500, B = $10,000, C = $12,500.  Nearly all sophisticated software patents are of  B or C complexity.  Chemical inventions are mostly C complexity.

Some Ballpark Cost Figures for Filing a Patent

$10,000, on the low end, to file a patent.  “But [Ronald J. Riley, president of the Professional Inventors Alliance USA] and other small inventors also knock the present system:  High legal bills — inventors can expect to spend $10,000, on the low end, to file a patent; most of that is attorney’s fees.” How much does it cost to file a patent?  What is the cost of a patent?  (Akweli Parker, “Inventor’s reality,” Philadelphia Inquirer, Philadelphia, Pennsylvania, March 23, 2006)
$10,000 – $15,000 as a range.  Attorney fees charged for preparing a patent application. “[M]ost companies spend between $10,000 and $15,000 in attorney fees to prepare the application.” Patent attorney fees. (Dean Turman, patent attorney at MacCord Mason, Greensboro, North Carolina quoted in Michelle Cater Rash, “Restructuring raises patent fees, could hinder startups,”Business Journal Serving the GreaterTriad Area, April 11, 2005)

Complex Inventions Cost More

Complex inventions cost more to prepare than simple applications.  More work and more expertise are required to file patent applications on complication technology.  For example, one should expect patents covering chemical compounds or processes to involve more work and expertise than inventions to simple machines.
Many large firms break inventions down into tiers of complexity.  Extremely simple inventions would fall into the least costly tier, hovering around $6,000.  (Extremely simple inventions could include coat hangers, paper clips, earmuffs, etc).  Highly complex inventions would fall into the most costly tier, ranging from $15,000 and upwards.  Highly complex inventions would include pharmaceutical, medical imagine devices, complicated software, and the like.
One back-of-the-envelope way to determine the cost is to ask the level of education required to work with the technology.  Would a machinist or technician understand the invention?  Or would understanding the invention require a PhD?
According to Julia Feldmeier of the Washington Post, filing a patent application “can easily run more than $20,000, depending on the complexity of the patent…” See “Any Bright Ideas?; How Local Inventors Try to Capitalize on That ‘Aha!’ Moment,” The Washington Post, March 4, 2007).
 

Best Law Schools for Learning Patent Law

Best IP Law Schools

US News and World Report just published their list of the “Best Intellectual Property Law” Schools.

Best IP Law Schools with Evening Programs

Harold Wegner circulated a list of these schools, broken down to the Top Ten within that List that have an evening program.  Mr. Wegner’s motivation for the selection was that “more and more successful patent students are welcoming the chance to attend 1L classes “full time”, but then get a full time patent job in their 2L and 3L years while taking law school classes at night.”

These are the best IP Law School that offer an evening program.

My Experience Learning Patent Law at GW’s Evening Program While Working for Finnegan During the Daytime

I attended the George Washington University Law School while working for Finnegan.  I think that this was the best way to learn patent law.  Working through law school gave me practical experience from 9-5 each day and then academic context from 6-8pm each night.  In my opinion, either of these taken alone does not provide the synergy of having them together.  By learning this way, I often tried to apply what I was learning in law school to the work that I was doing for clients during the day.  I also approached my lecture sessions from the standpoint of trying to extract useful bits that I could apply to my work at the firm.
Another plus to working through law school is that many firms will help pay for school.  When I was at Finnegan, my “Student Associate” position came with tuition reimbursement.  That’s a big win.  However, it becomes taxable income, so law school still is not free once you take that into consideration.
There were a few notable downsides to working while going to law school.  First, it was time consuming.  Everyone complains about how hard it is to balance law school with work.  In my experience, it wasn’t a big deal.  I listened to lectures each night instead of watching TV.  And, having a “real job” during the day helped keep the law school experience in perspective.
Second, going to evening classes takes four years to get a JD.  That’s an extra year of law school. This can be condensed to 3.5 years by attending summer classes.  But, either way, you drag out the process.  For this reason alone, I knew many students who transferred over to full time.  If I could have had it my way, I would have done the full time (3 year) route but also worked full time.
 
 

Patenting Clean Energy Technology

Big Opportunities for Patenting Clean Energy Technology

Thanks to Houston Brown for this great guest post on clean energy innovation.  The post is particularly timely in view of the American Chemical Society’s upcoming conference on Chemistry & Materials for Energy.  The conference will be held from March 16-20, 2014 in Dallas, Texas.
IP professionals often analyze patent-related activities in aggregate by defining the ‘patent landscape’ for a technology or field of study. The landscape analogy provokes images ranging from barren deserts to dense forests, and variances in patenting activity can be just as wide. The current landscape for clean-energy technology is best related to a freshly ploughed farmer’s field – much care has been taken to ensure the conditions for growth are ideal, and the time to plant is now.

The U.S. Department of Energy Recognizes the Importance of Clean Energy Technology

There is no mistaking how important clean energy technologies are to the US Department of Energy. The primary goal of their latest strategic plan is to “Catalyze the timely, material, and efficient transformation of the nation’s energy system and secure U.S. leadership in clean energy technologies”.1 To this end the DOE has contributed more than $6.8 billion towards renewable energy development between 2003 and 2012,2 of which about $950 million has been directed towards university-based R&D. While academic scientists across all six renewable energy platforms (solar, wind, tidal, geothermal, hydro, biomass) have benefited from the funding, the budget allocations have been far from equal. In 2004 more than 75% of clean energy R&D dollars were directed towards projects related to solar, bio energy, and hydrogen/fuel cells.3
So, what do cadmium telluride photovoltaics, nano-structured biomass pyrolysis catalysts, and solid oxide fuel cells, have in common? They are all the result of innovations at the interface between chemistry and materials science. Chemistry and materials science are driving the transformation of the nation’s energy system.  The DOE appears to appreciate this contribution.

Opportunities for Chemical Contributions to Clean Energy Technology

While substantial funding has been in place for decades, the development of clean energy technologies from chemistry and materials has been slow. Major advances towards understanding fundamental processes have been prerequisites for the development of commercializable technologies. Fortunately, the state-of-the-art for many applications has advanced to the point that ideas that once seemed impossibilities are being reduced to practice.  The inventive steps that underlie the progress in these areas are not only highly desirable; they are often patentable.

Clean Energy Startups Recognize the Importance of Patenting Clean Energy Technology

Clean energy startups around the country have begun leveraging strong chemistry-based patent portfolios to gain access to an abundance of government-incentivized financial support. The trend is reflected in patent activity at the USPTO, where applications for solar, bioenergy, and hydrogen fuel cell technologies have grown steadily since the early 2000’s.4 While the increase in activity is significant the landscapes remain largely under developed.4 This finding manifests frequently in prior art citation patterns from the USPTO database, where patent applications in these fields consistently turn to peer-reviewed journal articles to describe the prior art, presumably due to a dearth of related patents.
Academic scientists that are inventing in these key areas should not delay in capitalizing on this opportunity. Working with an expert IP professional during the process of reducing an invention to practice enables scientists to draft patent claims covering the most desirable parts of the patent landscape. The clean energy patent landscape is primed for growth, now is the time for chemists and materials scientists to stake their claim.

Overview of Patent Process for Inventors

Overview of the Patenting Process

The overview of the patent process will likely depend on who you ask.

The overview of the patent process will likely depend on who you ask.


Can you give me an overview of the patent process?  Inventors and founders often ask me for an overview of what to expect when getting a patent.  That’s a fair question.  And there are a variety of approaches to answering it.  The answer really depends on the person’s perspective. A patent secretary will view the process differently from a patent agent, who will view it differently from a government official, etc..
For example, according to a patent lawyer, the United States Patent and Trademark Office (“USPTO”) provides an overview of the “Process for Obtaining a Utility Patent.”  Understandably, the USPTO focuses largely on the procedural aspects of getting a patent.  After all, the USPTO is concerned with how each applicant navigates their system.
I come at the patent process from the inventor’s perspective.  I am most concerned with maximizing value from the patent process.  So my “overview” is a little bit different.  I focus on comparing the invention to the state of the art and using that comparison to draft the most valuable patent claims possible. Below, I have outlined this process.  Notably, it looks quite different from other “overviews” of the patent system.

Inventor Focussed Overview of Getting a Patent

My overview of getting a patent can be distilled into 9 steps, which I’ve outlined below.  Notably, a patent professional would add “client development” and “engagement” before step #1.  (For many patent professionals, getting the client consumes about 30% of all time).  Likewise, a patent litigator or transactional attorney would care only about step #9.  A patent secretary would focus primarily on the paperwork involved in steps 6-8.

  1. Extracting the Invention – Organizing all available information about the invention by interviewing the inventors, usually multiple times.
  2. Studying the Invention – Studying all available information provided by interviewing the inventors and reviewing documents provided by the inventor.
  3. Comparing the Invention to the Prior Art – Independently evaluating the invention from the standpoint of someone skilled in the relevant art; Determining similarities and differences.
  4. Drafting Patent Claims – Defining the invention in a manner that emphasizes its patentable aspects.  This involves applying the analysis in step #3 to synthesize definitions with the greatest likelihood for covering valuable property within the following twenty years.
  5. Drafting Patent Application(s) – Drafting supporting descriptive material.  This material often provides definitions for key terms in the application, along with examples, and background information.
  6. Filing Patent Application(s) – Formatting the application from step #5 to conform with the USPTO’s standards for patent applications.  Then, filing the patent application with the USPTO and paying the required fees.
  7. Arguing for Patentability – After filing a patent application, the application sits “pending” at the patent office for years.  See Stats.  After waiting, a patent examiner examines the claims and (almost always) rejects them as a “first action.”  At that point, the applicant must address the examiner’s reasons for rejecting the claims–usually through some combination of arguing or amending the claims.
  8. Grant of Patent – After agreeing on a set of patentable claims, the Applicant pays the issue fee and the USPTO grants a patent.  The Applicant is then responsible for paying maintenance fees 3.5, 7.5, and 11.5 years following the grant.
  9. Enforce or License Patent – A patent provides the right to exclude others from making, using, or selling the invention that is defined in the claims.  This right to exclude is the source of all value – a monopoly – the ability to prevent competitors from entering the market.  That right may be sold (licensing the patent) or enforced against competitors via a patent infringement lawsuit.  This later route is also called patent litigation.

 

Patenting "Academic" Science

Why Academic Scientists Should Use the Patent System

Academic scientists often regard the patent system as beyond their reach.  I recently communicated with a few hundred members of the American Chemical Society, encouraging them to make better use of the patent system.  An overwhelming majority considered the patent system to be something reserved for finished, commercialized technology.  Not true.
Academic scientists should embrace the patent system for a variety of reasons.  The post below outlines a few of them, including benefits to reputation and funding sources.

Patenting Academic Research – Background

After a decade of economic stagnation US Congress passed the Bayh-Dole Act in 1980 as an attempt to tie university-based innovations to the private sector. Among other things, the legislation provides ownership rights for inventions developed with government support may be granted to directly to the inventor or university. The Bayh-Dole act incentivizes academic scientists using federal research grants to bring their products to market.  Response to the act has been impressive; In 1980, 390 patents were awarded to university-based entities, by 2009 the number increased to 3088.
Historically, the vast majority of university-based patent applications were associated with the country’s elite research institutions, but university-based patent activity is becoming increasingly widespread. Bibliometrics ­– the analytics of patent and publications records – provides clear evidence that academic scientists are reaping the rewards of engaging the patent system, and the rewards are numerous.

For Academic Scientists, Patent activity and publication productivity are positively correlated

‘Publish or perish’ is the mantra of the scientific community for a reason: journal submissions are the metric by which academic scientists are measured. Bibliometric studies at both the national and international level indicate that inventor-scientists (academic scientists with one or more patent applications) publish significantly more than their non-patenting colleagues who work in similar fields and who have similar career characteristics.
In addition to increased publication rates, there is a direct relationship between patent-activity and publication-impact factors; inventor-scientists are more frequently cited by their peers, and their work is more frequently accepted in top-tier journals.
Even after controlling for individual heterogeneity, the event of a patent is likely to alter the natural flow of publications produced year-by-year. In this particular point, all available studies agree that the relationship between patent and paper scores is a positive one.”

For Academic Scientists, Patenting Benefits Funding, Networking, Collaboration

Data collected from the curriculum vitae of more than 1200 US academic scientists provide further insight into the benefits of engaging the patent system. Relative to their non-patenting colleagues, inventor-scientists receive more private-sector funding. The contributions are significant; in 2009 industry contributed more than $3.2 billion to academic research and development in the United States.
Ties to industry are also associated with enhanced career mobility. Inventor-scientists spend more of their between academia and industry, typically in consultant or directorship roles. These activities are associated with the development of broad career networks and increased potential for interdisciplinary collaboration.

For Academic Scientists, Patenting Provides One Indicator of Better Science

Of course, many scientists are driven less by external factors like funding and promotion, and more by the intrinsic rewards of problem solving and discovery. At this level, publication and patenting activities present similar intellectual challenges. Great patents and publications arise from the same foundations: creativity, originality and novelty. Many inventors feel they improve the quality and the state-of-the-art character of their fundamental research questions as a result of the insights they obtain from engaging with the patent system.
Given the increasing number of university-based patent applications, it is likely that the number of inventor-scientists will continue to rise.  Arguably, the scientific community will be stronger for it.

Patenting Provides a Potential Revenue Stream for Academic Scientists and Institutions

Another potential upside arising from patents is that the academic community could incur a significant monetary benefit.  By using the patent system, these pioneering, academic scientists could claim their advances.  By claiming their contributions, they can create intellectual property in those contributions.  If commercially applied, that property would create a revenue stream–directly benefiting the inventor-scientists and their academic institutions.

Better Brewing Through Chemistry

Brewcraft's Rogue Brutal Kit comes with all ingredients EXCEPT yeast, along with instructions for brewing the beer

Improving Brewing with Chemical Principles

From the standpoint of patent law, brewing could be divided into three categories of invention.  These categories are as follows: compositions, processes, and devices.
Notably, each category of invention includes some sort of chemical component.  Each Ingredient, intermediate, and finished product could be viewed as chemical composition.  Processes describe making or using those compositions (for example the steps in a recipe).  Equipment is used to manipulate or measure those compositions (for example, the carboy, funnel, airlock, etc.).
In an earlier article, we discussed patenting beer technology.  We noted that craft brewing is filled with innovative people, bound to rapidly improve this technology.  In this article, we discuss a chemist’s view of using two “kits” for  home brewing. The first kit is Rogue’s Brutal IPA using the Beercraft kit.  The second is Brewer’s Best Double IPA.  Both were brewed using the Brewer’s Best equipment kit.  The kits and equipment were purchased from Sound Homebrew in Seattle, Washington.

Brewing Process Steps from a Chemical Standpoint

Chemically speaking, the brewing process can be broken down into these fundamental steps:

  1. EXTRACTING — Grain is steeped in warm-hot water, extracting certain components of those grains into the water, creating a “tea”.
  2. DISSOLVING — Sugar (provided as malt extracts) is dissolved in the boiling tea, creating a “wort.”
  3. EXTRACTING — Hops are boiled in the wort for varying lengths of time, extracting certain components of those hops into the wort.
  4. PHYSICALLY MANIPULATING —The wort is transferred to a fermenter and cooled.  At this stage, some of the undissolved solids may be physically separated  (e.g., filtering or decanting) from the wort.
  5. ADDING BIOLOGICAL REAGENTS — Yeast is added to provide a fermentation catalyst
  6. CONTROLLING REACTION CONDITIONS — The system is equipped with an airlock, isolating it from the surrounding atmosphere, thereby controlling the reaction conditions.

Each of the above steps requires the brewer to follow people-sized instructions with the hopes of producing favorable microscopic results.  The brewer adds tangible amounts of water, grains, sugars, and hops to a pot.  The brewer monitors the clock on the wall and the thermometer in the brew pot.  The brewer’s ultimate goal is producing an aqueous solution of molecules (beer) that is pleasing to drink.
Practically speaking, brewer can follow people-sized recipes and produce good beer with reasonable reproducibility.  Nevertheless, thinking about the underlying chemistry may provide some sources for future innovation.  The rapidly growing craft brewing community seems to be constantly looking for new and different beers.  Our hope is that focussing on the chemical underpinnings of brewing will create opportunities for making inventive beers.

Brewing Chemistry – Molecules, Time, Temperature, and Concentration

Brewing beer is chemistry.  Generally speaking, the progress of a chemical reaction depends on (1) the chemical regents, (2) the reaction time, (3) the reaction temperature, and (4) the reagent concentration.  The term “chemical regents” refers to the molecules in the reaction.  Different molecules behave differently.  Accordingly, the most important part of chemistry is understanding what molecules are in the reaction.  Chemical reactions proceed more rapidly at higher temperatures and higher concentrations.

Making beer is chemistry.  And craft brewers appreciate that hops are made of underlying molecules.

Chemical Reagents in Beer Compositions

The craft brewing community recognizes the importance of chemical reagents.  In particular, extreme brewers recognize the benefits of trying new combinations of ingredients in order to create different flavors.  Note, an “ingredient” to a brewer is a “chemical reagent” to a chemist.
One opportunity for further innovation in the craft brewing space could come from viewing the ingredients at the molecular level.  By understanding which molecules correspond to certain flavor properties, a brewer could control the reaction conditions to select for desired flavor properties.  The brewing community appreciates the molecular composition of certain ingredients during the hopping process.  Different varieties of hops are described in terms of their molecular compositions (alpha and beta acids).  Those hops are added to the boils at certain times in order to control how they convert into certain flavors.

Craft brewers should not limit themselves to thinking about hop chemistry.  Each other ingredient added to the beer also has a molecular composition.  Many of those molecules change and react during the brewing process.  For example, many ingredients react with the oxygen while being heated (in the boil) in the presence of oxygen (in the air).

Oxidation Chemistry in Brewing

Another potential opportunity for creating new beers could come from a better understanding of oxidation.  Oxygen is present throughout the brewing process.  Oxygen from the air reacts with many of the ingredients, chemically changing those ingredients to provide different flavors.  Additionally, oxygen is an important part of the initial fermentation process.
Thinking about how certain chemical ingredients react with oxygen could provide new ways to make different beers.  For example, the concentration of oxygen could be controlled rather than relying on the amount naturally present in the air.  One idea would be performing certain brewing steps under and inert atmosphere, by using nitrogen or argon.  By limiting the amount of oxygen present, the brewer could control how much certain flavor molecules oxidize.  Adjusting the amount of oxidation during brewing could lead to new flavor opportunities.  Limiting oxygen could also create opportunities for using higher temperatures and longer times without the negative oxidative reactions.  These sorts of techniques could give rise to new beer technology.
Oxygen is an important part of the fermentation process.   In Extreme Brewing, Sam Calagione advises that a homebrewer introduces oxygen into the wort by “rocking the baby” before sealing the fermenter.  Notably  oxygen is also present in the headspace of the fermentation vessel.  By varying the amount of oxygen present at various stages of fermentation, the brewer could improve the progress of the reaction.
The Llamas’ Brewing Company in Washington state appears to be the first company doing work in the air-free brewing space.

Chemical Concentration in Brewing

Lastly, a better understanding of concentration could provide some advantages to the home brewer.  Molecular concentration is extremely important in a finished beer.  For example, alcohol by volume (ABV), international bittering units (IU), a variety of aromatic compounds, and residual sugars play an important role in the beer’s flavor profile.  These important metrics are reported to 2 or 3 significant figures.  For example, the ABV in Great Divide Brewing Co.’s  Hercules Double IPA is reported at 10.0% (three significant figures).  Not 10% (one significant figure).  Despite the importance of concentration, many beer recipes treat concentration as relatively unimportant.
Concentration refers to the amount of a given molecule within a given volume.  (The standard is “moles per liter,” which is called the Molar concentration).  In the laboratory, all mass quantities are converted into moles in order to understand the number of molecules.  Then, for solutions, the concentrations are described as molar concentrations, to indicate the number of moles per liter of volume.  In the home brew beer recipes, the volumes used to make the beer are “approximate” and also imprecise.
Many beer recipes treat volume with relatively litter precision.  For example the Brewer’s Best Double IPA recipe instructed the brewer to bring the volume in the fermenter to  “approximately 5 gallons” before pitching the yeast.  Additionally, the glass carboys available at the Sound Home brew store did not provide any volume indicators.  Some very simple improvements to home brewing equipment could be made by providing better volume indicators on the apparatus and paying closer attention to volume.
