BATTERY

BATTERY

To most people in the 21st century, batteries are simply a convenient substitute if mains electricity is impractical or unavailable. But when the battery was invented in 1800 it was the first device capable of providing an electric current.

Alessandro Volta (Italy) was an eminent physicist who made a number of significant breakthroughs in the field of electricity and is commemorated by the use of his name for the electrical unit of potential difference, the volt. His most famous invention, the battery, came about as the result of a disagreement with another Italian scientist, Luigi Galvani.

In 1775 Volta invented a 'perpetual electrophorus': an early form of electrical induction machine that could be used to generate and store static electricity. It worked by rubbing cat fur across a rubber-coated metal plate to build up a static charge, and then transferring the charge to a Leyden jar; by repeating the process several times a large charge could be built up. (The Leyden jar was invented in 1745 at the university of Leyden, Netherlands, as a means of storing electric charge.) Static electricity and the Leyden jar were nothing new, but what Volta had invented was a means of accumulating an electric charge.

Volta's real breakthrough, however, came when he heard about the electrical experiments of anatomist Galvani. Galvani had noticed that dissected frogs' legs would twitch if they were part of a circuit involving two metals, and concluded that the muscles and nerves were the source of what he called 'animal electricity'. Volta disagreed, thinking that the current was more likely to be due to the connection between the two metals; he began experimenting with pairs of metals and discovered that he could generate an electric current if certain metals were submerged in acid. The result, in 1800, was Volta's greatest invention, the 'voltaic pile'. It was the world's first battery - a series of copper and zinc strips submerged in salt water that could provide an electric current rather that mere status electricity. The following year, Napoleon I (ruler of Italy since its conquest by France in 1796) bestowed the Legion of Honour on Volta, in recognition of the importance of his invention, and made him a Count.

How to Patent An Idea

How To Patent An Idea

Governments do not issue patents just for an idea.Ideas, thoughts or inspirations do not not qualify for a patent.
Expressions or publication of thoughts that are not inventions, like this page for example, are protected by copyright.
Publication of unique symbols or word designs are protected by trademark.
These are good tools as well, but how to patent an idea for an invention is dealt with differently than other ideas.

How To Patent Something

An invention idea is usually about how you can solve a problem. But you have to make the solution (an invention) before you can apply for a patent.It is something real and tangible. An invention must also be new, unique, and useful.

Patent Strategies

Lets say you have this idea that "socks should not get holes in them".This might be a good invention idea. Lots of people wear socks.
Most people would probably want socks that didn't get holes in them.
So you start thinking about how to patent an idea like this. But you can't get a patent for this idea.
This is an invention idea, meaning it gives you an idea for something you could invent - "a sock that doesn't get holes." There are ways to protect your idea before applying for a patent, which you can learn about on our website.

First Step

Once you have this idea, the very first thing you should do is conduct a patent search.If your patent search doesn't find anything like your idea, you could start working on your invention. You want to make your idea into an invention.
If you want to license your invention, you need to plan this while you're developing your idea.
As you progress with your invention you might experiment and test materials, spending long hard hours on your invention.
Let's say you invent a coating that you can put on wool thread. This makes the socks durable. You make some socks using this new wool material. They're comfortable and have a unique and different look to them.
But your new thread is not easy to work with so you adapt a sewing machine to make it easier to sew socks.
This was a lot of work and you actually have created more than just one invention.
You may feel ready to protect your invention by obtaining patents. But there are still other steps to take, which you can find on our website.

We Have Tools

A patent is just one tool we use to prepare our inventions.There are several tools we use to give our inventions a chance to become successful.

Trademark Logo

Logo

A trademark logo is a graphic symbol or design usually combined with type. It is a "mark" used to identify a brand of product or service.

Marketing

The "RR" of Rolls-Royce, the "three stripes" of Addidas, or the script text of Coca-Cola are logos - as are Mr. Clean, Playboy Bunny, Michelin Man, Mickey Mouse and the Gerber Baby.A well designed logo is an important marketing tool for inventors. It can effectively distinguish an invention from similar products or brands in the marketplace.
It can give immediate recognition for a product, or communicate a desirable impression that will allow a company to have a competitive advantage.

Licensing

A trademark logo is also a tool that helps to license an invention. It can become more valuable, or as valuable, as a successful invention because of collateral licensing opportunities.An inventor in San Diego invented durable surfing shorts. He designed a logo for his shorts, which was two footprints with ten circular toes and the name "Hang Ten". Today, it is licensed to manufacturers around the world for practically anything to do with surfing - earning millions in revenues.
Many companies, such as Gucci, Walt Disney and Starbucks, license their "marks" for use on other merchandise.
Trademark rights do not expire so long as the mark continues to be used. This is an effective strategy in extending the monopoly of an invention. Wham-O's flying disc trademark known as "Frisbee" is an example of the effectiveness of a trademark after a patent has expired.
Having a good trademark can help license your invention.It is an additional tool that can be included in a business plan as part of a marketing strategy. Trademarks are also relatively inexpensive to register, although you own the rights to your own design whether it is registered or not.

Definition of Trademark

The definition of trademark is any word, name or symbol that is used by a manufacturer or merchant to identify their goods as distinguished from those made or sold by others.Trademarks are of interest to inventors because they offer additional rights to those provided by patents.
They are sometimes confused with other types of identifying marks that have their own unique definitions.

Service Mark

A trademark that identifies a service, rather than goods, is known as a "service mark" in some countries. Television, telephone and transportation companies would be examples of services.Service marks are CNN, AT&T and FEDex. Service marks may also refer to the identifying features of a person, as in Oprah or the architectural features of a building or store, like McDonald's, Kentucky Fried Chicken or FotoMat.

Sound Mark

A definition of trademark that refers to a distinctive sound, associated with a product or service, is known as a "sound mark".The MGM "lion roar", the THX "digital sound" and the NBC "chimes" are sound marks.

Certification Mark

A "certification mark" is commonly included within the definition of trademark. It is the identifying words and/or symbols of an organization that "certifies" a characteristic of a product or service. It is used to assure consumers that a particular product or service meets certain criteria.Underwriters Laboratories "UL" and the Idaho Potato Commission's "Grown in Idaho" are certification marks.

Collective Mark

A "collective mark" refers to a trademark used by membership organizations. It is used by members to indicate their membership, such as the "AAA" mark for the American Automobile Association or the "NCAA" mark for the National Collegiate Athletic Association.

Trade Name

More on the definition of trademark

A "trade name" is a registered business name used by a company to identify itself when providing products or services. For example,The Proctor & Gamble Company uses the trade nameProctor & Gamble when selling it's trademark "Ivory" soap.

Brand Name

A "brand name" generally refers to how a merchant brands or uses their trade name, trademarks or other marks.Branding and brand recognition, refers to the experiences consumers have toward a product or service.
It is generally a marketing term that refers to how consumers are identifying with a product, service, company or person.
For example, a car manufacturer will have one of their vehicles used in a movie. The film may feature images of the vehicle, it's performance and trademarks.
It may be driven by the hero in the movie. The car company's name or slogan may be used in the dialog. This is called branding.

Making A Prototype

Costs

Making a prototype can be expensive, but there are ways for an inventor to reduce the costs in the early stages of development.Years ago when I was working in China, it amazed me how resourceful the Chinese were at making a prototype.
Today, they have all the modern equipment and facilities to manufacture anything - but they didn't have all that stuff when they started manufacturing exports.

China

What they would do was run around looking for materials, tools or machinery they could use for making a prototype. There was a great deal of co-operation amongst their businesses.They would assist each other because they all had the same objective - to manufacture products for export.
They also knew that they couldn't get orders unless they could make sample prototypes. If one business helped another to make a prototype, they would receive some sort of exchange in return - a referral, materials, orders , or some other consideration.
The most important thing was a referral or contact with a foreigner, the actual buyer of products.
I'll give you an example of how this works and then explain how you might use this information for making a prototype where you live and work.

Prototype

I was talking to a Major League Baseball team about a souvenir they could give to their fans attending games. The idea was a small "replica" baseball bat with a player's picture on it.Everybody thought it was a good idea but I needed some samples.
I went to China with pictures of baseball bats, players and some sketches to make a prototype. I was told it would take about a week. The person making it for me told me it wouldn't cost me anything but asked if I would meet some of his friends for lunch sometime.
I said "sure". So here is what he did.
He went to dozens of places looking for wood, tools, coating laminates etc. He also looked for people with skills that could help make my prototype.
In return for helping him, they would have lunch with me to talk business and exchange business cards.
I received my samples a week later, as promised, and they were really good. They looked like tiny wood baseball bats, and had a player's picture laminated on it with a plastic coating.
I also was given a surprise. A red velvet wood box.
Inside was a replica baseball bat made entirely of aluminum -with grip tape around the handle. I was stunned.
From that moment, and ever since, I came to realize they could make virtually anything.
Unfortunately, the souvenir baseball bat idea didn't work out. Having thousands of fans drinking beer in a stadium, armed with small "billy-club" baseball bats - wasn't something the baseball ownership felt comfortable with.
I eventually had lunch with everyone who helped with the prototypes - all thirty of them.

Resources

When you think of what you need in order to make a prototype, you should think in terms of where you could get your material, access to skills or equipment.For example, trades people such as welders or electricians have types of material and equipment that they use. It is surprising what assets and resources exist among the businesses in your area.
Colleges, universities and technical schools also have skills, equipment and facilities that could be a resource for making a prototype.
To avoid disclosure of your invention, you can have different non-confidential parts of it made at different places. In this way, you can assemble the parts and retain confidentially of your invention.
You can talk about your invention in general terms without disclosing your invention.
For example, my invention is a wireless device that extracts and stores energy from any type of battery. This tells you about the invention rather than how the invention is made or how it works. I could be even more general by saying my invention is about saving energy from batteries.

Tips

When asking people for help in making a prototype, without paying them anything or very little - you need to give them a reason for doing so.You could say you need to make a prototype to show investors and that you're trying to save money to pay your attorneys for a patent.
Most people find this quite understandable.
They all know lawyers are expensive, and most believe that the first thing you do when you have a good idea is to patent it.
You may also offer some other exchange. For example, I will give lectures to schools about inventing or some other topic as an exchange.
This is a good way to start making a prototype, keeping your costs low, until you have a final design that you may decide to have professionally made.

Invention Prototype

Purpose

An invention prototype is the physical evidence that your unique and new idea actually works.It is a functioning model of your invention and is proof of the problems it solves and/or the benefits it provides.
There is a two-fold purpose and a number of phases to making a invention prototype.
- Primary -
The primary purpose is to prove to yourself that your invention will work.
It is a research and development phase that will eventually produce a final "pre-production" model of your invention.
You develop your invention prototype to create a working model that is patentable and potentially profitable.
It allows you to test functionality and make improvements before moving forward. This is an important phase with respect to the patenting process.
If you patent your invention before finalizing your prototype you may not have included any improvements or you may make claims that are no longer a part of your invention.
You will probably make many prototypes before you finalize your product.

Depending on what your invention is - will determine whether you can make a prototype yourself or have it made for you.
If you have access/connections to materials - you may create a prototype yourself, or if not, you will need to make arrangements to have it made for you.
You will need to make drawings, schematics and/or diagrams of your product and it's functions. This process should provide an understanding of how your product will be manufactured - which determines the manufacturing costs.
- Secondary -
The secondary purpose is to prove to someone else that your invention works.

Reducing the costs of an invention prototype

During this phase you are attending to issues related to financing, patenting and licensing your invention or establishing a business to do so.This is where you have a final prototype that you will use, as one of your tools, to convince investors and/or licensees of the profitability of your invention.

Computer Generated Prototype

Constructing a fully functional invention prototype can be expensive and time consuming, however modern technology makes this process less expensive and faster.The drawings, schematics and/or diagrams of your invention prototype can be three-dimensionally created with computer software that is integrated and programmed with machinery.
This machinery can then make "all" or "parts of" your invention using the required materials in various molding processes.
This technology is known as CAD/CAM (computer aided design/computer aided manufacturing) and the prototyping process is called "rapid application development" or "rapid prototyping".
Companies that do this type of work specialized in different fields of manufacturing and tend to focus on certain types of products.
For example, a company may specialize in "rapid electronics prototyping" for circuit boards related to thermostats.

Prototype Companies

You can find these companies through a local university where the engineering departments have connections with them.
If you decide to use a prototype maker, you will want to check their references before using their services. You will also want to have the necessary agreements executed to protect yourself.
Most prototype companies charge an hourly rate for the work they do. You should ask for an estimate of time and cost.
Most reputable prototype makers depend upon their reputations for the work they do. They have a good idea about their time and costs.
You may want to stipulate a budget or "price cap" on the work. This prevents "padding" which means they may take longer and bill more hours than is warranted.
Like any relationship, working with an invention prototype company can be mutually beneficial - as both of you can benefit from each others connections.
