Patent Searches

Activity 3.2.1:  Have you ever had an idea that you thought would be great enough to patent? Did you talk to a patent attorney or expert about the process involving patents? If so, you discovered it is a detailed process and searching for existing patents can be tricky.

There are three main ways to search for patents on the United States Patent and Trademark Office’s (USPTO) website. These are keyword searching, number searching, and browsing using the manual of classification.

Interviews and Testimonials

Activity 3.2.2:  Often during the course of researching a topic, you will come across a personal testimonial or interview as to the effectiveness of a particular product or process. Just look at the exercise or dieting industry, where you will see numerous examples. During your research, you may come across one or more testimonials that will support the validity of your chosen need. It adds a personal touch to what could become dry research and emphasizes the human factor. For example, if you are concerned about the number of injuries caused by lifting heavy wheelchairs into cars, a logical place to look for people also interested in that would be at nursing homes or extended care facilities.

Pros and Cons

Activity 3.2.3:  Benjamin Franklin used the pros and cons listing technique when he was in the process of making important decisions. In his notes, he explains that he would take a piece of paper and fold it down the middle, creating two columns. One side would be reasons for an action and the other side would be reasons against the action. He would then list all the things he could think of in the appropriate column. When he was finished, he would strike the ones he felt cancelled each other out; the column with the most remaining would be the course of action he would follow. He very candidly tells of this being the way he chose his wife.

As you are graduating from high school and focusing on college, you will be faced with many decisions. Your choice of colleges will depend upon many of the following factors: available scholarships, courses of study offered, tuition cost, housing options, and minimum acceptance requirements. No doubt you will rank these considerations, and possibly others based on their importance to you. After you have compiled a list of colleges offering your course of study, you can decide which one satisfies most of your considerations. This is the type of informed decision-making engineers and many other professionals make everyday. It provides them with a justification for their choices that are based on objective considerations.
