Drug patent protection: How long is long enough? A recent Senate committee hearing on Bill S-17, Parliament's effort to comply with international trade rules by extending pharmaceutical patent protection to 20 years, inadvertently opened the door to a broader investigation of the inner workings of the country's pharmaceutical patent legislation.
The Virtual Currency Landscape. Virtual currencies such as Bitcoin are digital representations of value that function as a medium of exchange, a unit of account, and/or a store of value. In many cases, virtual currencies are âconvertibleâ currencies; they are not legal tender, but they have an equivalent value in real currency. In terms of value, Bitcoin is the most prominent virtual currency. As of late January 2015, one bitcoin equaled roughly $207 (though the value is volatile), and all bitcoins in circulation totaled $2.85 billion.
Digital currency, however, is a form of virtual currency that is electronically created and stored. Some types of digital currencies are cryptocurrencies, but not all of them are. So that leads us to the more specific definition of a cryptocurrency, which is a subset of digital currencies that uses cryptography for security so that it is extremely difficult to counterfeit. A defining feature of these is the fact they are not issued by any central authority.
