Do I Need a Local California Patent Attorney?

You Need the Right Patent Attorney:
One That Focuses on Inventors, Start-Ups, and Small Businesses

Most local Patent Attorneys in California focus on serving large corporations that provide a stream of patent work year after year. They are not enthusiastic about working with individual inventors and entrepreneurs with only one invention. Thus, individuals and small companies are usually passed off to an inexperienced junior Patent Attorney in the Firm with inadequate training and minimal oversight.

As rare as Patent Attorneys are, even fewer California Patent Attorneys focus on smaller clients, and therefore they are almost never found locally. That’s why Patent Law Firms with an entrepreneurial focus reach out nationally, since there are not enough individual inventors and entrepreneurs in any one local area to support such a highly specialized legal practice for a Patent Attorney in California.

Patent Attorneys are Licensed to Practice Nationally — You’re Not Limited to Only California Patent Attorneys

Patent Law is based on Federal Law, not State Law. Every Patent Attorney is licensed to practice nationally by passing the Patent Bar Exam given by the US Patent & Trademark Office. So, finding a Patent Attorney in California is not necessary.

California Patent Stats

#1 State for Most Issued Patents

As the state with the largest population, in addition to being home to technology center Silicon Valley, it’s no surprise that California produces more patents each year than any other state. In 2015, 28% of all U.S. patents were issued to California inventors. That means California patent attorneys are in high demand.

#1, #3, and #6 Universities for Most Issued Patents

The University of California has held the #1 spot for the most issued U.S. patents ever since NAI/IPO first began ranking the top 100 global universities in 2012.

For the 2018 ranking of the Top 100 Worldwide Universities Granted U.S. Utility Patents, Stanford University ranked #3 for issued U.S. patents and the California Institute of Technology (Caltech) ranked #6 for issued U.S. patents.

Silicon Valley Produces Half of All California Patents

With Silicon Valley producing almost half of all California patents, and over ten percent of all patents nationwide, it’s no wonder the U.S. Patent Office chose to open a satellite office in San Jose, CA for local California Patent Attorneys.

Hollywood Started as an Escape from Edison’s Patent Monopoly on Movie Making

Edison joined forces with other motion picture patent-holders to form the Motion Picture Patents Company (MPPC), essentially a monopoly of patent-holders. California became a refuge for filmmakers seeking to escape the oppressive MPPC monopoly on the East Coast, with the result that Hollywood ended up as the center of the movie business.

  • I began with an idea and a set of sketches. This idea that I had is now my company where I work full time.

    I began with an idea and a set of sketches. I had no idea what I was doing. I needed help. I found Russ Weinzimmer on the internet and gave him a call. He was in New Hampshire, I was in California. I had bad experiences in the past working remotely with people so I was hesitant to work with him. Once I spoke to him on the phone, I knew he was someone whom I could count on.

    Russ really took the time to explain to me the whole patent process and where I needed to be. He did it in such a way that I could plainly understand the process and the steps involved. He took the time to really understand my product and the reasons for it’s importance, both to me and to the end consumer. I felt that it was very rare for a patent attorney to invest so much time into a client before even discussing rates or cost.

    I ended up filing 3 initial patents with Russ. As we spoke we determined that we should do multiple patents to better protect my product. This made perfect sense to me as other variants could compete with my product. If we patented them all, I would be better protected. Once the patents were filed I went on to production of my product. Later on that year I filed a fourth patent documenting the changes made during the production stages of my product. This fourth patent was filed very quickly for me as my product was scheduled to be released to market. He and his associate Bob worked day and night to get the patent filed for me in time.

    I will say one thing, I was not the easiest client for Russ. This was the start of a new business for me, I had everything on the line. Because of this my nerves often got the best of me, and I would call Russ, concerned about one thing or another. Russ always had time for me. We would communicate at all hours of the day. One day he was on a walk and took the time to talk to me for a good 45 minutes. He really wants to help, and he makes sure his clients are all protected and at ease with the process.

    This idea that I had is now my company where I work full time. ... Read More

    Thank you Russ for helping me on my Journey.

  • They exceeded my HIGHEST expectations by a factor of four and made me think, “Russ never sleeps.”

    What a relief in finding a competent attorney who not only “gets it” and is personally available but who will also add value to projects both large and small. In this day and age your product needs the ‘Strategic Patent Law’ advantage.

    Russ’ analytical and ‘hands on’ approach helped me to realize what I had actually invented! Russ deconstructed our sustainable, mobile shelter and showed me that we had seven novel, patentable features within our ‘base design.’ In doing so, broader market protection was realized while numerous licensing and revenue streams were created. ...

    Can you imagine a 5-hour conference call with your patent attorney? This is exactly what I experienced during the course of working with Russ and his team of professionals. They exceeded my HIGHEST expectations by a factor of four and made me think, “Russ never sleeps.”

  • Without Russ's help, I never would have challenged USPTO's findings and would have missed out on the opportunity to get a patent for my invention.

    I want to thank you for the advice you gave me during our talk back in May. The USPTO had rejected all of my claims as being both obvious and anticipated by a prior invention. I was absolutely convinced that USPTO was right and that my invention was exactly the same as the prior invention. You advised me to carefully review the two inventions and not focus on their similarities but, instead, focus on their differences. I did as you advised and found several small differences, one of which I thought was significant. Based on that small but significant difference, I prepared a response to USPTO. Today I received a Notice of Allowance. Without your help, I never would have challenged USPTO's findings and would have missed out on the opportunity to get a patent for my invention. I can't thank you enough.

  • I frequently gave Mike our most difficult challenges, and he always exceeded my expectations.

    During his 17-year career at Cognex, Mike made many valuable contributions. Most recently, in his role as Vice President of Cognex Legal Department, Mike led the team of both internal staff and external law firms that successfully carried out the company’s litigation strategy to both protect our intellectual property and, as in our landmark case against Lemelson, to ensure that our customers would be able to purchase our products free from the threat of suits from patent trolls. But, it was his contributions during Cognex’s formative years that I value the most. During that time, he wore many hats and made significant contributions in areas ranging from finding and appointing distributors in Asia to the drafting and negotiating of numerous complex customer, supplier and partnership agreements. ... Read More I frequently gave Mike our most difficult challenges, and he always exceeded my expectations in getting the job done on time and on… and sometimes under… budget! Mike has a very sharp business mind. I would often involve him in business discussions even outside of his area of expertise because I knew that he would give me very thoughtful, analytic and unbiased input. He might not always tell you what you want to hear… and THAT is one of his most valuable strengths. Mike is also tenacious… of all the hundreds of people at my company, he best personifies one of our core values: Perseverance. He just doesn’t stop until the job gets done. Finally, Mike is a trusted advisor whose loyalty to the company is without question.

  • Our previous lawyer messed up our patent case. Russ corrected their mistake and got my patent granted.

    Russ is a great lawyer. He listened, didn't rush, explained things through thoroughly and made sure I understood all the legal jargon. He would even take my calls at pretty much any hour. It's nice to have a lawyer that you feel is really on your side, not just there to make money.

    Our previous lawyer messed up our patent case by submitting the application images wrong. Then tried charging us to fix his mistake. I immediately looked for a new lawyer and my first call was Russ. He had my back and was able to even prove that my previous lawyer messed up. He corrected their mistake and got my patent granted.

    Will definitely use him for my future intellectual property filings!

  • Anyone looking for a Patent Attorney who is efficient, knowledgeable, kind and whose fees are reasonable, call Russ Weinzimmer!

    Because of Russ Weinzimmer, I have recently been issued a Notice of Allowance for a patent on my invention - the Chlorine Genie, a chlorine generator for sanitizing water. It has been quite an experience! My company is in California. I began the patent work two different times with California Patent Attorneys. Both were woefully inadequate in answering my calls or following up with our discussions and moving ahead with the patent work.

    When I decided to find another Patent Attorney, my wife decided she should go to the internet and find someone who was highly recommended by people who had actually had experience with the attorney. This proved invaluable to us! ... Read More She found Russ Weinzimmer (Strategic Patent Law). I was a little uneasy about working with someone who could not come to my office, see my invention, and talk about the strategy for obtaining a patent, but my wife felt we should go ahead and call Russ.

    Even though we have never met Russ "eyeball to eyeball" he treated us with respect and encouragement from the very first telephone conversation. Russ answered my calls and emails in a timely manner. He worked closely with me in educating me as to the things I needed to do in order to give him the information he needed. We accomplished all the patent work by email and telephone and I felt I was getting his best efforts at all times.

    His assistant, Mary, has also been wonderful in relaying information and assisting me in any way needed. She had been efficient and kind in her dealings with me.

    I would encourage anyone looking for a Patent Attorney who is efficient, knowledgeable, kind and whose fees are reasonable to call Russ Weinzimmer! I am thrilled with the Notice of Allowance I have received from the Patent Office and will continue my relationship with Russ on all my future Patent Work.

  • I now have a Registered Trademark, and my business is thriving.

    Russ at Russ Weinzimmer & Associates, PC and his staff are a true top notch organization! When I first called Russ, I seriously had no idea where to start to establish a Trademark. He put me at ease from the first moment of our discussion, and jumped right in to educate me on the process. I was off and running. His Paralegal Lori kept me informed every step of the way. I had no doubt that I was in good hands. Fast forward … I now have a Registered Trademark, and my business is thriving. I cannot thank Russ enough for his hard work and perseverance. Russ is a true professional, and a real inspiration to everything good in this world.

    Rob Merrick

  • He would work day and night with me one on one and walked me through the process.

    Working with Russ on my project was great. I have never tried to get something patented before. He would work day and night with me one on one and walked me through the process. I am now patent pending. The man never sleeps!

Inventors Market New Product: ReeferShield

Inventors Market New Product: ReeferShield

The result of over a decade of prototyping and testing, the ReeferShield is a system of straps and pads that protect and secure the doors of refrigerated semi-trailers, called “Reefer Units”, while making it easy for drivers to open the doors for servicing or inspection.

The ReeferShield inventors developed a unique solution to an industry-wide problem, and successfully pursued patent rights, resulting in an issued US Patent. Then, Senior Associate Joe Carlen implemented an ambitious data-driven commercialization plan that continues to deliver real success for the Hadleys as they market their new product to trucking companies throughout the US and internationally.

Patent Attorney Costs:Flat Fees Work Better for Clients

Patent Attorney Costs:
Flat Fees Work Better for Clients

Instead of charging clients for every billable hour and each individual expense, the flat fee rate model charges clients a flat fee for specific work. In order to accurately quote a flat flee, the patent attorney needs to take the time to fully understand the client’s needs and create a plan to efficiently and effectively protect what matters to the client’s business. Thus, the value of the work becomes the focus of the engagement, rather than the attorney’s time.

The benefits to you are clear: You know what the final cost will be, and can budget accordingly. You don’t need to worry about going over budget and running out of money halfway through. You don’t have to pay extra for phone calls and emails when you have questions. You don’t get nickel-and-dimed for every minute and expense. You only pay for the actual work, and you don’t tie up money in retainer fees.

Patent Attorneys: Why Some Patent Law Firms Understand Your Situation Better

Patent Attorneys: Why Some Patent Law Firms Understand Your Situation Better logo interview with Russ Weinzimmer:

Many Patent Law Firms cater to corporate clients, so when individuals or small companies approach them, they don’t really get good attention. Invention Marketing Companies put the cart before the horse by marketing the invention before protecting it. Then as the inventor approaches the deadline to get a patent, they have run out of money or optimism.
