Career Highlight
Patent Attorneys
The Job: Patent attorneys and agents write and submit
patent applications for inventors. They represent the inventor in all
communications with the USPTO.
Working Conditions: These attorneys and agents spend a
majority of their time researching and preparing patent
applications. They can work within large corporations,
work in law firms, or be self-employed. Working
conditions are similar to other law professions.
Education and Training: Patent attorneys
and agents must apply to the USPTO to represent
inventors. To become registered with the USPTO,
people must pass an examination on patent law and
policies. They must also have at least a bachelor’s
degree in a science or an engineering discipline.
Those who meet the requirements and also have a law
degree are considered patent attorneys. The people
who do not have a law degree are titled patent agents.

Think Green
Green Materials
Green materials are considered environmentally friendly
materials that are alternatives to commonly used materials. To define
a material as being green, some criteria are: the material must not
be created from exhaustible natural resources; it must emit less
carbon dioxide emissions than other materials when processed; and
it must either be recyclable or be biodegradable. An example of a
green material is recycled paper. It doesn’t use new materials, it uses
different processing techniques, and it may be recycled again.

A skeleton frame carries the weight of the building, very similarly to
how the human skeleton carries the body. These developments made
high-rise buildings, or skyscrapers, possible. The first high-rise building
was built in Chicago in 1885. Built for the Home Insurance Company,
it was 10 stories tall. The exterior walls provided protection from the
weather. These walls, however, did not carry any load. This type of wall
is called a curtain wall because it merely hangs from the frame.
Today, high-rise buildings use two types of framework. The first
type is reinforced concrete. See Figure A. This type of framework is
cast on-site. Forms are erected around a network of steel rods. The
concrete is poured inside the forms. After the concrete has cured,
the forms are removed.

bolted or riveted together. See Figure B. This allows the beams to
expand and contract uniformly with temperature changes.
Once the frame is erected, the floor and roof are installed. The
exterior walls are then put in place. See Figure C. These walls can
be made of steel or aluminum panels, bricks, concrete blocks, sheets
of glass, or other materials.
The title of the world’s tallest building passes from skyscraper to

is currently the Burj Khalifa, built in Dubai, United Arab Emirates in
2009. There are, however, several skyscrapers in both the planning and
construction stages that will be taller. The Sears Tower in Chicago is the

Chapter 9 Activity A
Introduction
New inventions and innovations are created every day. You might never encounter
some of them. There are many inventions, however, that most of us use all the time.
These inventions have become part of our daily lives. Eventually, many of these inven-
tions, as great as they are right now, will become outdated. For example, it is impractical
to use the telegraph for long-distance communication today. It is important, however, to
understand that the invention of the telegraph led to other inventions we rely on today. In
this activity, you will examine an invention used today.
Procedure
1. Select one of the following inventions: the telephone, television, printing press,
automobile, airplane, telescope, laser, or single-lens reflex (SLR) camera.
2. Using the library or Internet, research your invention in order to answer the
following questions:
• Who invented the product?
• When was it invented?
• Why was it invented?
• What inventions led up to this invention?
• How does the invention work?
• What are the impacts (positive and negative) of the invention?
• What inventions have come from your invention?
• Was the invention patented?
3. Create a display (poster board) answering the research questions.
4. Present your display to the rest of the class.
Activity Overview
In this activity, you will investigate and determine the need for an invention, develop an
idea for the invention, and then present your idea using a stand-alone multimedia presenta-
tion; a documentation notebook; a model, or prototype; and an oral presentation.
Materials
• Presentation software.
• A three-ring binder with 8 1/2″ × 11″ pages.
• Materials for the model, or prototype (will vary greatly).
Background Information
Selection. Before selecting the theme for your project, consider past inventions and
innovations and current needs in each of the major divisions of technology:
• Medicine.
• Agriculture and biotechnology.
• Energy and power.
• Information and communication.
• Transportation.
• Manufacturing.
• Construction.
Use brainstorming techniques to identify several possible inventions and innovations
from each area. Select an idea for a final invention to meet an identified need. The
invention can be completely new, or it can be an improvement to an existing device,
system, or process.
Design. Research issues and gather information about the identified need. Work on
the design and details of the final invention. Design and construct a model, or prototype,
and visual aids that can be used to enhance the presentations.
Chapter 9 Invention and Innovation 223
Guidelines
• The invention should be realistic and have the potential to be workable.
• The multimedia presentation must be between two and four minutes long. This
presentation must be self-explanatory. The multimedia presentation should show the
development of the idea of the final invention.
• The oral presentation should not be longer than five minutes. The model, or
prototype, must be part of this presentation. The goal of this presentation is to
convince the audience that the invention is needed and has real potential.
• The following items must be included in your documentation notebook:
• A cover sheet.
• The title, or name, of the identified need and a brief description.
• The title, or name, of the invention and a brief description.
• Photos of the model, or prototype, of the invention.
• Relevant information about the stand-alone multimedia presentation.
• The following items must be included in your multimedia presentation:
• The title of the invention.
• The identified need and information about it.
• Information about the design and brainstorming processes.
• Information about the invention, including the model.
• An assessment of the invention and its potential for being a workable device,
system, or process.
Evaluation Criteria
Your project will be evaluated using the following criteria:
• The effectiveness of the multimedia presentation and documentation notebook to
document your work as you investigated and developed an idea for an invention.
• The effectiveness of the oral presentation to convince the audience that the invention
is needed, is workable, and has the potential for a return on investment.
