Categorizing Technology

There is no one way of dividing technology into categories. Whereas once it might have been simple to classify innovations such as machine-based or drug-based or the like, the interconnected strands of technological development mean that advancement in one area might be replicated in dozens of others. For simplicity’s sake, we will look at how the U.S. Patent Office, which receives patent applications for nearly all major innovations worldwide, addresses patents. This regulatory body will patent three types of innovation. Utility patents are the first type. These are granted for the invention or discovery of any new and useful process, product, or machine, or for a significant improvement to existing technologies. The second type of patent is a design patent. Commonly conferred in architecture and industrial design, this means someone has invented a new and original design for a manufactured product. Plant patents, the final type, recognize the discovery of new plant types that can be asexually reproduced. While genetically modified food is the hot-button issue within this category, farmers have long been creating new hybrids and patenting them. A more modern example might be food giant Monsanto, which patents corn with built-in pesticide.

Anderson and Tushman (1990) suggest an evolutionary model of technological change, in which a breakthrough in one form of technology leads to a number of variations. Once those are assessed, a prototype emerges, and then a period of slight adjustments to the technology, interrupted by a breakthrough. For example, in terms of portable data storage, the first mainstream device was a floppy disk–a square, plastic object larger than a playing card, which in its final iteration held 1.4 megabytes of data (or less than a single high-resolution photo). Until the early 2000s, these were common formats, and students and professionals would regularly carry several of them. Floppy disks were improved and upgraded, then replaced by higher- capacity Zip and Jaz disks, which were then replaced by flash drives. This is essentially a generational model for categorizing technology, in which first-generation technology is a relatively unsophisticated jumping-off point that leads to an improved second generation, and so on.
